	abstract = {A wide variety of vanadium-containing complexes have been tested, both in vivo and in vitro, as possible therapeutic agents for the oral treatment of type 2 diabetes mellitus. None so far has surpassed bis(maltolato)oxovanadium(IV) (BMOV) for glucose- and lipid-lowering in an orally available formulation. Ligand choice is clearly an important factor in pharmacological efficacy of vanadium compounds as insulin enhancing agents. In this study, we kept the ligand and dose the same, varying instead the metal ion bound to the maltolato ligand in a series of binary complexes of neutral charge. A requirement for vanadyl ion as the metal ion of choice was apparent; no other metal ion tested served as a suitable substitute. Amongst [MoO2](2+), Co(II), Cu(II), Cr(III), and Zn(II), only [MoO2](2+) and Co(II) showed any hypoglycemic activity at the ED50 dose for bis(maltolato)oxovanadium(IV), 0.6 mmol kg(-1) by oral gavage in streptozotocin (STZ)-diabetic rats within 72 It of administration of compound.

	abstract = {The reaction between [Cr3O(O2CCH3)(7)(H2O)] ({\textquoteright}basic chromium acetate{\textquoteright}) and an excess of nicotinamide (na) at 120 degrees C, followed by dissolution of the mixture in water and addition of PF6-, led to the isolation of the first Cr(III)-nicotinamide complex [Cr3O(O2CCH3)(6)(na)(3)](+) (1). Crystals of the compound 1 . PF6. 3CH(3)CN were subjected to a detailed X-ray structural analysis. The three N-bonded na ligands, which occupy axial positions at the corners of the triangular basic chromium acetate, are nearly co-planar with the Cr3O system. The three Cr-N(na) bond distances are in the range 2.121(8)-2.128(8) Angstrom. Two of the na ligands on each cluster form four hydrogen bonds with two ligands from a neighboring cluster, via their amide ends with N...O distances of 2.88(1)-2.92(1) Angstrom. Magnetic susceptibility measurements of a powdered sample of 1 . PF6. 3CH(3)CN over the range 2-300 K showed that the three Cr(III) ions were antiferromagnetically coupled with J -10.4 cm(-1). There was no evidence for intermolecular magnetic exchange between the two Cr3O centers which are connected via hydrogen bonds. (C) 2000 Elsevier Science S.A. All rights reserved.},

The samples were analyzed by electron spin resonance spectrometry (ESR). Accelerated fixation of CCA by steam treatment initially produced a strong chromium(V) ESR signal, which quickly decreased. Complete reduction of Cr(VI) to Cr(III) was achieved in 2 hours by steaming. Samples stored under ambient conditions still exhibited a moderately strong chromium(V) signal after 44 days. Oven drying of the CCA-treated samples for four days, failed to convert all of the chromium(V) intermediate to the trivalent form. Leaching of CCA-treated samples, confirmed that fixation was best achieved with the steam treatment. Oven drying caused the samples to leach large amounts of copper and smaller amounts of chromium and arsenic.},

	abstract = {{Reduction of [Cp*Mo(NO)I2]2 [CP* = eta-5-C5Me5] by sodium amalgam in THF at -30-degrees-C in the presence of an isomeric mixture of (E)- and (Z)-1,3-pentadiene affords two isolable isomers of Cp*Mo(NO)(eta-4-trans-1,3-pentadiene), one yellow (1A) and one red (1B). The most significant feature of the solid-state molecular structure of 1A is the fact that the transoidal (E)-1,3-pentadiene ligand is coordinated to the molybdenum with its methyl substituent pointing away from the cyclopentadienyl ring. The spectroscopic properties of 1B are consistent with it possessing a similar orientation of its (Z)-1,3-diene methyl substituent. This observation establishes that even though the Cp*Mo(NO) fragment in 1A and 1B exerts the electronic influence to bind the diene ligands in a twisted, transoidal fashion, steric interactions determine which face of the diene ligand can best accommodate this electronic requirement. Cyclic voltammetry studies have been carried out on two representative diene-containing compounds, namely CpMo(NO)(eta-4-trans-2,5-dimethyl-2,4-hexadiene) and CpMo(NO)(eta-4-cis-2,3-dimethylbutadiene) (Cp = eta-5-C5H5), in order to establish the redox properties of these types of complexes. The cyclic voltammograms indicate that both diene complexes are reasonably stable with respect to addition of electrons, since no reduction behavior is observed to the limit of the CH2Cl2 solvent (ca. -2 V). On the other hand, each of the complexes is quite readily oxidized and each exhibits three irreversible oxidations before the solvent limit of ca. +2 V. These redox properties are in accord with the results of Fenske-Hall molecular orbital calculations previously performed on the CpMo(NO)(eta-4-butadiene) model systems. Consistently, CpMo(NO)(eta-4-trans-2,5-dimethyl-2,4-hexadiene) does not undergo concomitant reduction when treated with acetylenes but rather effects a coupling between the diene ligand and the alkyne to produce a eta-4 (eta-3, eta-1) ligand in which the eta-3-allyl portion of the ligand is oriented endo with respect to the cyclopentadienyl ring. Thus, when the alkyne employed is 1-phenylpropyne, the resulting complex is CpMo(NO)[eta-4-C(Me)2CHCHC(Me)2C(Me)C(Ph)] (2), whose molecular structure has been established by specialized NMR spectroscopic techniques and by single-crystal X-ray crystallography. The reaction between CpMo(NO)(eta-4-trans-2,5-dimethyl-2,4-hexadiene) and 1,7-octadiyne affords two major isomers of a similar organometallic product. Finally, the isolable products of the reactions between CpMo(NO)(eta-4-trans-diene) and HX (diene = 2,5-dimethyl-2,4-hexadiene},
