	abstract = {Novel complexes of Ga3+ and In3+ were synthesized with two hetero donor phosphinophenolate ligands (PO-, ortho-phenoxydiphenylphosphine; MePO-, 5-methyl-2-phenoxydiphenylphosphine). RPO- (R = H, Me) binds in a bidentate fashion through both the hard O and the soft P donor atoms to In3+, whereas, it only binds Ga3+ through the O donor. Electrochemical synthesis proved to be a practical synthetic approach to In-2(PO)(3)Cl-3, In(PO)(3) and In(MePO)(3). [In(MePO)(H2O)Cl-2](2) and Ga(HPO)Cl-3 were synthesized from MCl3 (M = In and Ga, respectively). Both dimetallic indium complexes, [In(MePO)(H2O)Cl-2](2) and In-2(PO)(3)Cl-3, incorporate phenolate oxygen atoms bridging the two metal ions. Each pair of In atoms are in a distorted octahedral geometry in each complex, with the former complex having a coordination sphere of PO3Cl2 for both indium metal ions and the latter showing a coordination sphere of PO3Cl2 for one indium and P2O3Cl for the other. Ga(HPO)Cl-3 is a zwitterionic complex, with Ga having a OCl3 coordination core. All these complexes were fully characterized by a variety of techniques including X-ray crystallography.},

	abstract = {{The reaction chemistry of the potent insulin-mimetic agent bis(maltolato)oxovanadium(IV) (abbreviated BMOV or VO(ma)(2)) is reported. VO(ma)(2) (log K-1 = 8.80(2), log K-2 = 7.51(2), log beta(2) = 16.31(3)) has a rich coordination chemistry, forming a number of V(IV) and V(V) derivatives. In aqueous solution it is slowly oxidized by molecular oxygen to [VO2(ma)(2)](-) (log K-1 = 7.5(1), log K-2 = 6.2(1), log beta(2) = 13.7(1)); in alcohols a variety of V(V) analogs VO(OR)(ma)(2) (R = CH3, C2H5, i-C3H7) are formed by aerial oxidation. All these vanadate complexes can be interconverted by reaction with the appropriate alcohol or water. In addition, the six-coordinate V(IV) pyridine adduct VO(ma)(2)py can be formed and this undergoes oxidation to V(V) complexes much more slowly, demonstrating that a vacant coordinate site is required for the coordination of O-2 to VO(ma)(2) before inner-sphere oxidation can take place. V-51 NMR and electrochemistry have been studied as a function of pH; a complete study of the aqueous chemistry of VO(ma)(2) and [VO2(ma)(2)](-) has been undertaken because the oral activity of VO(ma)(2) as an insulin-mimetic may be related to the chemical properties of the two compounds in water. Oral gavage studies in STZ-diabetic rats have been performed which showed that the intact complex is required for activity and that the presence of a biologically compatible reducing agent, ascorbic acid, neither interferes with nor augments the insulin-mimetic effect of VO(ma)(2). The X-ray structures of VO(ma)(2) and the cis-VO2 compound K[VO2(ma)(2)]. H2O have been determined; crystals of VO(ma)(2)[BMOV] are monoclinic, P2(1)/n},
