	abstract = {The complexity of H-1 NMR spectra of solutes in partially ordered solvents such as liquid crystals increases rapidly with the number of spins. Spectra of simple solutes with sufficient symmetry and containing not too many spins (typically <= 8) are readily analyzed. The analysis of larger spin systems is more difficult, and often impossible. In this paper we present the application of a general automated evolutionary algorithm to solve the highly complex proton NMR spectrum of the 12-spin system pentane, a solute that interconverts rapidly among several symmetry-unrelated conformations. The interpretation of the spectral parameters that are obtained from the analysis requires the use of a model to connect relative orientational orders in symmetry-unrelated conformers.},

Specifically. H(DMSO)(2)[P(1,2-O2C6H4)(3)] and H(DMF)(2)[P(1,2-O2C6H4)(3)] have been isolated as crystalline solids. The downfield shifts of the acidic proton in their H-1 NMR spectra are consistent with its expected high acidity. The molecular structures of H(DMSO)(2)[P(1,2-O2C6H4)(3)] and H(DMF)(2)[P(1,2-O2C6H4)(3)] reveal that the protons in each are O-bound by either DMSO (x2) or DMF (x2). The N-H stretching frequency for the Oct(3)NH[P(1,2-O2C6H4)(3)] ((V) over bar (N-H) =3129 cm(-1)) is identical to that observed for trioctylammonium tetrafluoroborate ((v) over bar (N-H) = 3129 cm(-1)), suggesting that the basicity of these two weakly coordinating anions is similar. A preliminary investigation of the effectiveness of H(DMF)(2)[p(1,2-O2C6H4] in the protonolysis of metal-alkyl bonds was undertaken. Treating (dppe) pdMe(2) [dppe = 1,2-bis(diphenylphosphino)ethane] with H(DMF)(2)[P(1,2-O2C6H4)(3)] affords either [(dppe)pd(NCMe)Me][P(1,2-O2C6H4)(3) (1:1 ratio) or [(dppe)pd(NCMe)(2)(][P(1,2-O2C6H4)(3)](2) (1:2 ratio), both of which are structurally characterized.},

The harmonic vibrational frequencies of the two most stable cis-enol forms were calculated at the 133LYP level of theory using 6-3 1 G** and 6-311 ++G** basis sets. We also calculated the anharmonic frequencies at the B3LYP/6-31G** level of theory for these two stable cis-enol isomers. The calculated frequencies and the Raman and IR intensities were compared with the experimental results. The energy difference between the two stable cis-enol forms, calculated at the MP2/6-31G** level, is only 3.42 U/mol. The observed vibrational frequencies and intensities in the gas phase are in excellent agreement with the corresponding values calculated for the two most stable conformers. However, the observed IR and Raman frequencies also indicate coexisting of both tautomers in the liquid phase and in solution. According to the theoretical calculations, at the B3LYP/6-31 1++G** level, the hydrogen bond strength for the most stable conformer is 54.45 U/mol, about 2.4 kJ/mol less than that of the corresponding conformer of TFAA. These results are in agreement with the obtained experimental data. (C) 2007 Elsevier B.V. All rights reserved.</p>},

Herein we discuss an improved synthesis of these compounds from easily obtainable amino acids by means of a solid-phase methodology. Interestingly, we obtained two products of the same mass following our final macrocyclisation, relating to a similar distribution of products described in some previous reports. One of these products was the desired amatoxin; Pro(2)-Ile(3)-S-deoxo-amaninamide 1b. The other compound, after thorough investigation, was confirmed to be the epimer Pro(2)-D-allo-Ile(3)-S-deoxo-amaninamide la, not an atropisomer structure as previously suggested in syntheses of related amanitin analogues. Crystallographic data of la confirms the presence of a beta II-turn, rather than a PI-turn common to the natural toxin and 1b. This difference explains the large variation in CD spectra, although it seems to have relatively little effect on the bioactivity in vitro. These data provide new insights into the bicyclic amatoxin structure.},

In the predictions of relative stability of C-50 isomers, PM3 is an efficient method in the first step for sorting out the most stable isomers. HCTH with 3-21G predicts very good geometries for C-50, similar to the performance of B3LYP/6-31G(d).

	abstract = {The NMR spectra of four solutes, used as probes of liquid crystal orientational order, were analyzed. For each solute, samples were prepared at different solute concentrations, and the concentration dependence was used to extrapolate zero-concentration properties. The mean-field (Maier-Saupe) model when applied to solutes neglects solute-solute interactions and assumes all solutes in a mixed-solute sample see the same average environment. The first assumption is only valid as one approaches zero concentration, while experiments are typically carried out at concentrations between 0 and 10 mol \%. The solute concentration dependence has in the past been "scaled out" using an internal solute reference as an orientational standard. We measured the concentration dependence of the orientational order parameter and calculate the corresponding interaction energies based on a mean-field interaction potential for a solute. We find agreement at the 3\% level between experiments for different solutes while using (i) the zero-concentration values as solute-dependent orientational references and (ii) scaling to either order parameters or interaction energies; these two scalings gave equivalent but not identical results. We find, too, that errors inherent in the experiment and the calculations will limit attempts to refine the theory to push the comparisons beyond the 2\% level.},

They are at present formed by 17 elements, including the post transition metal mercury. Most are generated in superacids: the Lewis superacid SbF5 and the conjugate Bronsted-Lewis superacid HF-SbF5. Thermally stable salts are formed with the superacid anions [Sb2F11](-) and [SbF6](-). Many of the cations are superelectrophilic, with metals in oxidation states of +2 or +3. Three different synthetic routes are developed: reductive (A) or solvolytic carbonylations (B) and oxidative methods (C). Considerable progress has been made by replacing the Lewis superacid SbF5 as reaction medium by the conjugate Bronsted-Lewis superacid HF-SbF5. This allows reactions to proceed faster in a homogeneous phase and to produce crystalline materials. In total 27 mostly recent molecular structures have been obtained, including that of [Ir(CO)(6)] [SbF6](3)(.)4HF, the first HF solvate with one of the HF molecules coordinated in an isotridentate mode to three carbon atoms of the cation. Due to the electrophilic nature of the carbonyl carbon in fluoroantimonate salts of metal carbonyl cations, extended structures are formed via significant interionic C{\textendash}- F contacts. A new a-bonded carbonyl, (CF3)(3)BCO, which has been fully characterized, expands the existence range of metal carbonyl cations to group 13. The large amount of spectroscopic and structural information accumulated is used to present a conceptually simple bonding model.},

Variable-temperature H-1 NMR spectra of the Pd-2(1) complexes Pd2X2(dMPM)(2) (X = Cl, Br, or I; the P-P ligands in the Pd-2 complexes are always bridged, but for convenience, the mu-symbol is omitted) show the complexes to be fluxional in solution, the barriers to a ring-flipping process being DeltaGdouble dagger = 37.9, 39.0, and 43.2 +/- 0.9 kJ mol(-1) for the chloro, bromo, and iodo complexes, respectively. Treatment of Pd2X2(P-P)(2) (X = Cl or Br) with X-2 generates the stable, face-to-face Pd-2(II) derivatives trans-Pd2X4(P-P)(2), while oxidation of Pd2I2(P-P)(2) complexes with I-2 generates a new type of symmetrically di-iodo-bridged, five-coordinate complexes Pd2I2(mu-I)(2)(dmpm)(2) and Pd2I2(mu-I)(2)(depm)(2). The molecular crystal structures of four dipalladium(II) complexes are described: trans-Pd2Cl4(dmpm)(2).2CHCl(3), trans-Pd2Br4(dmpm)(2), trans-Pd2Cl4(depm)(2), and Pd2I2(mu-I)(2)(dmpm)(2). Solution NMR and UV-vis absorption spectra are consistent with the solid-state structures determined by X-ray diffraction. The stability of the dimeric Pd(II) complexes is attributed primarily to ligand steric factors.},

	abstract = {Gentle thermolysis of the allyl complex, (CpW)-W-*(NO)(CH2CMe3)(eta(3)-H2CCHCMe2) (1), at 50 degreesC in neat hydrocarbon solutions results in the loss of neopentane and the generation of transient intermediates that subsequently activate solvent C-H bonds. Thus, thermal reactions of 1 with tetramethylsilane, mesitylene, and benzene effect single C-H activations and lead to the exclusive formation of (CpW)-W-*(NO)(CH2SiMe3)(eta(3)-H2CCHCMe2) (2), (CpW)-W-*(NO)(CH2C6H3-3,5-Me-2)(eta(3)-H2CCHCMe2) (3), and (CpW)-W-*(NO)(C6H5)(eta(3)-H2CCHCMe2) (4), respectively. The products of reactions of 1 with other methyl-substituted arenes indicate an inherent preference of the system for the activation of stronger arene sp(2) C-H bonds. For example, C-H bond activation of p-xylene leads to the formation of (CpW)-W-*(NO)(CH2C6H4-4-Me)(eta(3)-H2CCHCMe2) (5) (26\%) and (CpW)-W-*(NO)(C6H3-2,5-Me-2)(eta(3)-H2CCHCMe2) (6) (74\%). Mechanistic and labeling studies indicate that the transient C-H-activating intermediates are the allene complex, (CpW)-W-*(NO)(eta(2)-H2C=C=CMe2) (A), and the eta(2)-diene complex, (CpW)-W-*(NO)(eta(2)-H2C=CHC(Me)=CH2) (B). Intermediates A and B react with cyclohexene to form (CpW)-W-*(NO)(eta(3)-CH2C(2-cyclohexenyl)CMe2)(H) (18) and (CpW)-W-*(NO)(eta(3)-CH2CHC)(Me)CH2CbetaH(C4H8)CalphaH (19), respectively, and intermediate A can be isolated as its PMe3 adduct, (CpW)-W-*(NO)(PMe3)(eta(2)-H2C=C=CMe2) (20). Interestingly, thermal reaction of 1 with 2,3-dimethylbut-2-ene results in the formation of a species that undergoes eta(3) {\textendash}> eta(1) isomerization of the dimethylallyl ligand following the initial C-H bond-activating step to yield (CpW)-W-*(NO)(eta(3)-CMe2CMeCH2)(eta(1)-CH2CHCMe2) (21). Thermolyses of 1 in alkane solvents afford allyl hydride complexes resulting from three successive C-H bond-activation reactions. For instance, 1 in cyclohexane converts to (CpW)-W-*(NO)(eta(3)-C6H9)(H) (22) with dimethylpropylcyclohexane being formed as a byproduct, and in methylcyclohexane it forms the two isomeric complexes, (CpW)-W-*(NO)(eta(3)-C7H11)(H) (23a,b). All new complexes have been characterized by conventional spectroscopic methods, and the solid-state molecular structures of 2, 3, 4, 18, 19, 20, and 21 have been established by X-ray crystallographic analyses.},

	abstract = {An X-ray diffraction study on syn-Pd2Cl2(dppmMe)(2), syn-1, shows an unusual boat-like conformation of the eight-membered Pd2P4C2 ring. This conformation, containing equatorial Me groups, facilitates access of the Pd-Pd bond to small molecules such as CO, SO2, and elemental sulfur or selenium, and makes the syn isomer more reactive than anti-1. A comparison of bond angles around the Pd and P atoms in the syn- and anti-isomers reveals a more strained geometry of the former, which may also contribute to the stronger propensity of syn-1 to form A-frame adducts. Solution NMR/NOE studies on syn- and anti-1 and their (mu-Se) adducts reveal the structural rigidity of these complexes; the Me groups inhibit the interchange of axial and equatorial positions on the bridging methine C-atom, and solution structures correspond to those in the solid state. The X-ray structure of Pd2Cl2(dppm)(2) is, as expected, like that of the corresponding bromo, complex; both are analogous to that of anti-1 which adopts a chair conformation within both the fused, five-membered rings.

The lowest lying transitions in the electronic absorption spectrum of DHBD-bound DHB occurred at 299 nm, compared to 305 nm for the monoanionic DHB species in buffer. In contrast, the corresponding transitions in neutral and dianionic DHB occurred at 283 and 348 nm, respectively, indicating that DHBD-bound DHB is monoanionic. These binding-induced spectral changes, and the use of custom-designed optical fiber probes, facilitated UVRR experiments. The strongest feature of the UVRR spectrum of DHB was a Y8a-like mode around 1600 cm(-1), whose position depended strongly on the protonation state of the DHB. In the spectrum of the DHBD-bound species, this feature occurred at 1603 cm-1, as observed in the spectrum of monoanionic DHB. Raman band shifts were observed in deuterated solvent, ruling out dianionic binding of the substrate. Thus, the electronic absorption and UVRRS data demonstrate that DHBD binds its catecholic substrate as a monoanion, definitively establishing this feature of the proposed mechanism of extradiol dioxygenases. This conclusion is supported by a crystal structure of the DHBD:DHB complex at 2.0 Angstrom resolution, which suggests that the substrate{\textquoteright}s 2-hydroxyl substituent, and not the 3-hydroxyl group, deprotonates upon binding. The structural data also show that the aromatic rings of the enzyme-bound DHB are essentially orthogonal to each other. Thus, the 6 nm blue shift of the transition for bound DHB relative to the monoanion in solution could indicate a conformational change upon binding.

	abstract = {Although an efficient DFT method using the generalized transition-state model to calculate core-electron binding energies had been successfully applied to over 200 cases, with an average absolute deviation of only 0.21 eV from experiment, a new DeltaE(KS)(PW86-PW91)/cc-pCVTZ model based on total Kohn-Sham energy difference was recently developed. Not only was the model error-free, but also the average absolute deviation for 32 cases studied was found to be 0.15 eV. In this study, we first confirm the excellent performance of such a DeltaE(KS) approach with 46 new cases, with the result that the average absolute deviation from experiment for the 78 cases remains at 0.15 eV. With such consistent accuracy, this new method is applied to the peptide bond. The model molecules studied in this work include formamide, N-methylformamide, N,N-dimethylformamide, acetamide, N-methylacetamide, N,N-dimethylacetamide, and two model dipeptides, one cyclic and one acyclic. The difference in the computed nitrogen core-electron binding energy between the two model dipeptides is found to be 0.85 eV, several times our average absolute deviation. This may be of interest to other workers studying other aspects of the peptide bond.},

	abstract = {The synthesis, structural characterization, and solution behavior of hafnium complexes stabilized by the potentially tridentate ancillary ligand [P2Cp] ([P2Cp] = (eta (5)-C5H3-1,3-(SiMe2CH2PPr2i)(2))) are described. The reaction of [P2Cp]Li with HfCl4(THT)(2) produces the hafnium trichloride complex [P2Cp]HfCl3 (1), the structure of which was determined by X-ray crystallography. Trichloride 1 is isostructural with the analogous zirconium complex [P2Cp]ZrCl3 (2) in the solid state, but in solution 1 exists as an equilibrium mixture of two isomers that interconvert by fluxional phosphine coordination. Treatment of 1 with 2 equiv of KCH2Ph, followed by thermolysis, yields the first structurally characterized hafnium alkylidene complex, [P2Cp]Hf=CHPh(Cl) (3). A crystal structure determination obtained for 3 shows this complex to be isostructural with the zirconium analogue [P2Cp]Zr=CHR(Cl) (4). The primary difference between the Hf systems presented here and the previously studied Zr analogues is that metal-ligand bonding is stronger in the former, which accounts for shorter bond distances, a greater degree of chemically inertness, and the divergent solution behaviors observed for the trichloride derivatives 1 and 2.},

	abstract = {The (A) over tilde (2)Sigma(+)-(X) over tilde (2)Pi(i) electronic transition of jet-cooled germanium methylidyne has been recorded in the 730-555 nm region by laser-induced fluorescence techniques. The radical was produced in a pulsed electric discharge using tetramethylgermane as the precursor. The band system consists of perpendicular and vibronically induced parallel bands with upper state frequencies of nu(2){\textquoteright}=638/497 cm(-1) and nu(3){\textquoteright}=990/952 cm(-1) for GeCH/GeCD. The (2)Sigma(+)-(2)Pi(3/2) components of the 0(0)(0) bands of GeCH and GeCD and the 2(0)(1) band of GeCH have been recorded with sufficient resolution to assign the transitions of the Ge-70, Ge-72, Ge-74, and Ge-76 isotopomers. The rotational constants of the various hydrogen and germanium isotopomers were used to derive the following molecular structures: r(0)"(Ge-C)=1.775 79(21) Angstrom, r(0)"(C-H)=1.0673(12) Angstrom, r(0){\textquoteright}(Ge- C)=1.673 66(8) Angstrom, and r(0){\textquoteright}(C-H)=1.0589(5) Angstrom. The ground state germanium-carbon bond length is typical for a Ge=C double bond, but in the excited state it corresponds to a triple bond. This is a consequence of promotion of an electron from a nonbonding sigma orbital to a pi bonding orbital to form the ...sigma(1)pi(4)((2)Sigma(+)) excited state. In this study we provide the first experimental value for the length of the germanium-carbon triple bond. (C) 2000 American Institute of Physics. [S0021-9606(00)01619-6].},

The formation of a complex depends on the bose (hydroxide or acetate) and the size of the respective Ln(III) ion. All complexes were characterized by infrared spectroscopy, mass spectrometry, and elemental analyses; in some cases, X-ray diffraction studies were also performed. The structures of the neutral mononuclear [Yb(L1)(NO3)], dinuclear [Pr-2(L1)(2)(NO3)(H2O)]NO3.CH3OH and [Gd-2(L1)(2)(NO3)]NO3.CH3OH.3H(2)O, and trinuclear [Gd-3(L3)(2)(CH3- COO)(4)(CH3OH)]ClO4.5CH(3)OH and [Sm-3(L1)(2)(CH3COO)(2)(NO3)(2)(CH3OH)]NO3.CH3OH.3.65H(2)O were solved by X-ray crystallography. The [LnL(NO3)] or [Ln(2)L(2)(NO3)](+) complexes could be converted to [Ln(3)L(2)(X)(n)(CH3-OH)](+) complexes by the addition of 1 equiv of a Ln(III) salt and 2-3 equiv of sodium acetate in methanol. The trinuclear complexes were found to be the most stable of the three types, which was evident from the presence of the intact monocationic high molecular weight parent peaks ([Ln(3)L(2)(X)(n)](+)) in the mass spectra of all the trinuclear complexes and from the ease of conversion from the mononuclear or dinuclear to the trinuclear species. The incompatibility of the ligand denticity with the coordination requirements of the Ln(III) ions was proven to be a useful tool in the construction of multinuclear Ln(III) metal ion arrays.},

	abstract = {Hexakis/carbonyl iron(LI) undecafluorodiantimonate(V), [Fe(CO)(6)][Sb2F11](2) is conveniently prepared by the oxidative carbonylation of Fe(CO)(5) with XeF2 as external oxidizer in the conjugate Br phi nsted-Lewis superacid HF-SbF5. The colorless compound crystallizes from the reaction medium in high purity. The molecular structure is obtained by single-crystal X-ray diffraction. The cation is a regular octahedron, while the vertex-shared di-octahedral [Sb2F11](-) anion is distorted from D-4h symmetry by bending and rotational processes, due to significant interionic interactions, primarily of the FC type. Washing of [Fe(CO)(6)][Sb2F11](2) with anhydrous HF results in an unusual elution of SbF5 and the quantitative conversion to hexakis(carbonyl)iron(II) hexafluoroantimonate;(V) [Fe(CO)(6)][SbF6](2) The molecular structure of the salt shows octahedral ions with slight tetragonal distortions for the cation (elongation) and the anion (comprsssion). Both salts are thermally stable up to 150 degrees C, The averaged bond distances and the vibrational wavenumbers of [Fe(CO)(6)](2+) are nearly identical in both compounds. The [Fe(CO)(6)](2+) cation, the first and so far only isolated and structurally characterized dipositive, superelectrophilic carbonyl cation formed by a 3d-metal, is further characterized by a normal coordinate analysis (NCA). The obtained force constants are compared to those of the isoelectronic molecule Cr(CO)6. Changes in pi-back-bonding affect the F-CO/CO and F-CO/MC interaction force constants more strongly than the stretching force constants F-CO and F-MC All 13 fundamentals of [Fe(CO)(6)](2+) are detected and assigned with the help of the data obtained from the normal coordinate analysis and density functional calculations published previously. The electronic ground state (1)A(1g), of the [Fe(CO)(6)](2+) cation is established by magnetic susceptibility measurements of polycrystalline [Fe(CO)(6)][SbF6](2) and [Fe(CO)(6)][Sb2F11](2) between and 300 K. The magnetic impurity formed during synthesis is identified as Fe[SbF6](2) which has iron(II) in high spin (T-5(2g)) ground state. Consistent with a diamagnetic ground state are the single line in the Fe-57 Mossbauer spectrum (i.s. = -0.003(8) mm s(-1) relative to alpha-Fe), obtained on polycrystalline samples and the single sharp line in the C-13 NMR spectrum in DF solution at 178 ppm with J (Fe-57-C-13) of 19.2 Hz.},

For example, the thermolysis of 1 in benzene solution generates quantitatively Cp*W(NO)(eta(2)-CPhCH2)(Ph) (2) The thermolysis of 1 in solutions of methyl-substituted arenes such as toluene or p-, m-, or o-xylene provides mixtures of aryl and benzyl vinyl complexes of the general formulas Cp*W(NO)(eta(2)-CPhCH2)(aryl), Cp*W(NO)(eta(2)-CPhCH2)(eta(1)-benzyl), or Cp*W(NO)(eta(2)-benzyl)(eta(1)-CPh=CH2). Similarly, the thermolysis of 1 in (Me3Si)(2)O affords Cp*W(NO)(eta(2)-CPhCH2)(CH2SiMe2OSiMe3) (10). Mechanistic and kinetic studies support the proposal that the formation of A from 1 by elimination of silane is the rate-controlling process in these reactions. Intra- and intermolecular selectivity studies reveal that the strongest C-H bond (yielding the stronger M-C bond) is the preferred site of reactivity, as expected. Dual C-H bond activation of aliphatic hydrocarbons occurs during the thermal activation ;of I in solutions of these substrates. Consequently, metallacycles of the form Cp*W(NO)(eta(2)-CH(eta(2)-Ph)CH2CH(R)CH2) [(11)R = Pr-n; (12)R = Bu-n; (13)R = Bu-t; and (14)R = OEt] result from the dehydrogenation of n-pentane, n-hexane, 2,2-dimethylbutane, and diethyl ether, respectively. This dual C-H activation process displays a selectivity for substrates that contain an ethyl substituent. Dual C-H bond activation of 2,3-dimethyl-2-butene in the presence of 1 under thermolysis conditions regioselectively affords Cp*W(NO)(eta(3)-endo-CH2C(Me)C(Me)CH2(eta(1)-CPhMe)) (15), Attempts to trap acetylene complex A with PNMe3 result in the formation of the metallacyclopropane complex Cp*W(NO)(CH2SiMe3)(eta(2)-CH2CPh(PMe3)) (16). All new complexes have been characterized by conventional spectroscopic methods, and the solid-state molecular structures of compounds 11, 15, and 16 have been established by X-ray diffraction methods.},

The solution H-1- and P-31{H-1}-NMR spectra are consistent with a C-20 symmetric species in solution. The X-ray crystal structure shows the hydride to be monomeric, and free from interaction with either salt (LiCl) or external base (Et2O). The coordination of both phosphines of the macrocycle to the metal center is found in the solid state. Solution molecular weight measurements are consistent with a monomeric structure. The gallium hydride syn-GaH[P2N2] (5) is synthesized by the addition of LiGaH4 to syn-MCl[P2N2] (M = Ga (2), In (3)). This species is unstable and could only be characterized in solution. Reduction of syn-MCl[P2N2] (M = Ga (2), In (3)) with KC8 yields the reduced, dimeric species {syn-M[P2N2]}(2) (M = Ga (6), In (7)). The solution H-1- and P-31{H-1}-NMR spectra are consistent with C-2v symmetric species in solution. The X-ray crystal structures of the gallium and indium complexes confirm the presence of unsupported metal-metal bonds in both cases. The features of the solution H-1- and P-31{H-1}-NMR spectra suggest that both dimers are fluxional in solution. (C) 1999 Elsevier Science S.A. All rights reserved.},

The quadrupole and spin-rotation coupling constants have been used to show that the electronic environment surrounding the boron nucleus of all three species is very similar.

The results from four spectra were combined to yield structural information and the order matrix in each solution. The structure of the ring is very close to that of 1,3-dichlorobenzene, and that of the ethenyl group very close to that of ethenyl-benzene. The dihedral angle between the ethenyl group and the aromatic ring is found to be 454 +/- 1.0 degrees, and the C-CC=C angle is found to be 127.3 +/- 0.3 degrees.},

That tunneling splitting is consistent with a twofold torsional barrier of 58.2(4) cm(-1). The minimum energy configuration has the C-C-F plane orthogonal to the plane of the phenyl ring. This is proved by the observed planar moment, P-CC, which is 16.88 u-Angstrom(2), a value compatible with only this geometry, and supported by the fact that only a-and c-type (not b-type) transitions were observed.

Reaction of [CpCr(NO)I](2) with [NBu4]I provides [NBu4][1], and halide abstraction from [NBu4][1] with 2 equiv of AgOTf affords [NBu4][2]. The weakly-bound OTf- ligands of [NBu4][2] are readily displaced by Br- to produce [NBu4][3]. The dichloro complexes [NEt4][4] and [PPN][4] are obtained by treating [CpCr(NO)Cl](2) with [NE4]Cl and [PPN]Cl, respectively. Use of acetonitrile as reaction solvent allows generation of the requisite [CpCr(NO)Cl](2) directly from CpCr(NO)(CO)(2) and PCl5, a marked improvement over previous synthetic routes to this dimer. Similar halogenations of Cp*Cr(NO)(CO)(2) in NCMe provide access to the previously unknown [Cp*Cr(NO)I](2) (5), and [Cp*Cr(NO)Cl](2) (6), halo-bridged, and dimers. The solid-state molecular structure of [PPN][4]. CH2Cl2 has been established by single-crystal X-ray crystallography to be a normal three-legged piano stool. The one-electron oxidation of [4] has been investigated both chemically (by reaction with [Cp2Fe](+)) and electrochemically (by cyclic voltammetry). These studies suggest that upon oxidation a high-spin CpCr(NO)Cl-2 complex is initially formed which then rapidly releases NO. Extended Huckel molecular-orbital calculations have been performed on [4], [CpCr(CO)(3)](-), and [CpCrCl3](-), three CpCr-containing anions with ligands of varying pi-bonding capabilities. Correlations between their orbital energies and electron occupancies and a rationale for the lability of the NO ligand in neutral CpCr(NO)Cl-2 are provided.},

Using force constants which are available from the literature, derivatives of the dipole moments were transformed into the representation of the normal coordinates of vibration, and the results were compared with the experimental data on the infrared intensities.

However, the NMR spectra arising from even relatively small molecules oriented in such solvents can be so complex as to defy analysis. There is demonstrated here a frequency-selective modification of the basic multiple-quantum NMR experiment which is capable of measuring otherwise difficult-to-obtain information in favorable spin systems.

Finally, stabilization of the highly electrophilic cations by coordination to CO leads to isolable complexes, unprecedented in transition-metal chemistry in their structural, spectroscopic and bonding characteristics.

	abstract = {The pure rotational spectra of five isotopic species of nitrosyl chloride were measured using a cavity pulsed microwave Fourier-transform spectrometer. Some a-type transitions of all five isotopomers, and some weak b-type transitions of four of these isotopomers were measured in the 4-26 GHz frequency range. Precise values for the rotational constants and the quartic centrifugal distortion constants were obtained. The rotational constants were used in structure determinations and the centrifugal distortion constants were used in a refinement of the harmonic general valence force field. A harmonic central valence force field was also calculated. Hyperfine structure in these transitions arising from quadrupole and spin-rotation coupling interactions was also observed. Diagonal and off-diagonal quadrupole coupling constants and diagonal spin-rotation coupling constants of both the chlorine and nitrogen nuclei were determined. The principal quadrupole coupling constants were evaluated and used to calculate the approximate ionic character of the N-Cl bond. The spin-rotational coupling constants were used to calculate the diamagnetic shielding factor for the nitrogen nucleus; the magnitude of this value indicates a fairly ionic N-Cl bond.},

	abstract = {In addition to the numerous and varied examples of organometallic and coordination compounds where carbon monoxide functions as a pi-acceptor ligand, there is a small but select group of derivatives where the CO-metal bonding relies predominantly on a-bonding only. The metal derivatives, which include Pt(CO)(2)Cl-2 known since 1868, are formed by electron-rich metals (Pd, Pt, Ag and Au), in oxidation states +1 and +2, are cationic in nature, and are for the most part thermally stable. Their generation in strong protonic and Lewis acids (HSO3F, HSO3F-SbF5 and liquid SbF5) allows convenient synthesis. The predominance of sigma-bonding results in unusual spectroscopic properties, such as <(nu)over bar>CO stretching vibrations as high as 2280 cm(-1), relative to 2143 cm(-1) in free CO, and C-13 chemical shifts which are 180-130 ppm rather than 190-220 ppm for classical transition-metal carbonyls. Consequently two basic principles, the synergic bonding model and the rule of 18, fail for these complexes. Recent structural studies point to the importance of secondary OC...OS or OC...FSb contacts, which in place of pi-backdonation provide for a measure of charge compensation both in solution or in the solid state. This review concentrates on very recent (since 1990) developments in this field, which is expanding rapidly beyond the transition metals.},

A harmonic force field has been calculated to derive ground-state average and estimated equilibrium geometries. The description of the normal modes in terms of internal coordinates is discussed. Chlorine and fluorine hyperfine structures have been resolved, allowing quadrupole coupling (including chi(bc) for the isotopomers containing O-18) and spin-rotation constants to be determined. Variations in the chlorine quadrupole coupling constants with different isotopomers have allowed the CI quadrupole tenser to be diagonalized and indicate that its z-axis coincides with the SCI bond.},

	abstract = {{The preparation of a series of dinuclear complexes of zirconium and tantalum is presented in an effort to determine factors involved in the coordination mode of the bridging dinitrogen ligand. Reduction of ZrCl3[N(SiMe2-CH2PR2)2] (R = Pr(i) and B(t)) with Na/Hg under N2 generate the corresponding dinitrogen complexes {[(R2PCH2-SiMe2)2 SiMe2)2N]ZrCl}2(mu-eta2:eta2-N2); the X-ray crystal structure of the dark blue derivative having R = Pr(i) shows that the dinitrogen unit is bridging in a planar side-on bonding mode. The N-N bond distance is 1.548(7) angstrom, which is the longest such distance for any dinitrogen complex reported. Molecular orbital calculations on this molecule indicate that the N2 unit bonds in a side-on fashion due to the unavailability of one of the d orbitals on each zirconium that would normally be involved in a pi-bond with the antibonding pi*-orbitals of the N2 moiety. This particular zirconium d orbital is unavailable due to the ancillary tridentate ligand which positions the amide donor (and the chloride) to overlap effectively with this d orbital. The results of this MO study also show that the HOMO has delta-symmetry. When the related derivative Zr(eta5-C5H5)Cl2[N(SiMe2CH2PPri2)2] is reduced under N2, the corresponding dinuclear derivative {[(Pri2PCH2SiMe2)2N]Zr(eta5-C5H5)}2(mu-eta1:eta1-N2) has the bridging dinitrogen unit end-on. In this case, the MO analysis shows that the cyclopentadienyl ligand overlaps with that zirconium d orbital which could form the delta-molecular orbital of the side-on mode; as a result, the end-on form is generated. A similar argument can be used to rationalize the end-on binding mode of the dinitrogen unit in the related tantalum derivatives {[(Pri2PCH2SiMe2)2N]Ta=CHR}2(mu-eta1:eta1-N2) (R = Bu(t), Ph), since now the alkylidene unit effectively overlaps with the same d orbital Crystals of {[(Pri2PCH2-SiMe2)2N]ZrCl}(mu-eta2:eta2-N2)-CH3C6H5 are monoclinic},

Methods for in situ formation of corresponding mixed bis(thiolate) species are also given. 1 is generally unreactive toward thioethers, although with propylene sulfide cct-Ru(eta-2-S2) (CO)2L2 is produced. Metathesis reactions of cct-RuCl2(CO)2L2 with NaSR salts yield 3 (R = aryl) or, when R = Et, cct-RuCl(SEt)(CO)2L2 or [L(CO)2Ru(mu-2-SEt)2(mu-3-SEt)Na(THF)]2 (4), depending on reaction conditions. The complexes are characterized by IR spectroscopy, H-1, P-31, and, in some cases, C-13 NMR spectroscopy, and for 2g and 3g (R = SC6H4pMe) and 4, X-ray crystallography. All three complexes crystallized in the space group P1BAR. For 2g},
