	abstract = {The complex [Cu(2,3-pydcH)(2)], (1), (2,3-pydcH(2) = 2,3-pyridinedicarboxylic acid) is a chain polymer. Two ligands occupy the equatorial plane of each tetragonally elongated octahedral Cu2+ coordination sphere, chelating through the pyridine nitrogen and one oxygen of the deprotonated 2-carboxylic acid group; the axial positions are occupied by long bonds to a 3-carboxylic acid oxygen of adjacent Cu(2,3-pydcH)(2) repeat units. This polymeric chain motif also appears in two heterometallic complexes incorporating the doubly deprotonated dicarboxylate ligand species 2,3-pydc; namely [Cu(2,3-pydc)(2)][Na-2(H2O)(6)(mu-H2O)(2)], (2), and [Cu(2,3-pydc(2)][Mn(H2O)(6)]center-dot2H(2)O, (3). In 2, the chains are cross-linked via a novel disodium cation [Na-2(H2O)(6)(mu-H2O)(2)](2+) to form a 2D sheet structure. In 3, the chains carry a formal 2- charge per copper centre, with charge neutrality achieved by the presence of isolated [Mn(H2O)(6)](2+) complex cations in the lattice. The structural and magnetic properties of these three species are compared. (C) 2003 Elsevier Ltd. All rights reserved.},

	abstract = {The controlled reaction of the Ta(V) trimethyl species [P2N2]TaMe3, where [P2N2] = PhP(CH2SiMe2NSiMe2CH2)(2)PPh, under 0.5 atm of hydrogen gas produces a partially hydrogenated Ta(V) species, [P2N2]TaMe2(H), of unknown structure. Under 4 atm of hydrogen gas, further hydrogenation does not produce the complex [P2N2]TaH3; instead, reduction of the tantalum center occurs to yield the dinuclear Ta(IV) hydride ([P2N2]Ta)(2)-(mu-H)(4). This diamagnetic tetrahydride fails to react with many reagents, including ethylene and carbon monoxide; however, upon addition of iodomethane, {([P2N2]Ta)(2)(mu-H)(4)}I-+(-) is produced as a paramagnetic green crystalline solid. The number of hydrides in this reaction product was confirmed by a deuterium labeling study. The results of a variable-temperature magnetic susceptibility study of this tetrahydride cation can be partially modeled with the Curie-Weiss law and a large correction for temperature-independent magnetism. Ab initio calculations using density functional theory were performed in an attempt to further understand the influence of the macrocyclic ligand in the bonding in these complexes.},
