The oxovanadium(IV) template was formed with the reaction between vanadyl sulfate pentahydrate, 2-hydroxybenzophenone-S-allylthiosemicarbazone, and 3-methoxysalicylaldehyde. synthesized complex, along starting ligand, subjected to UV-Vis, FTIR, mass, magnetic measurement. square pyramidal structure proven single-crystal X-ray diffraction method. Stronger crystals were π-π interactions, which al...

A range of mostly new oxovanadium(IV) complexes is described. They contain coordinated Schiff bases, made from simple dipeptides (glycylglycine, glycylsarcosine, L-alanylglycine, L-alanyl-L-alanine, D,L-alanyl-D,L-alanine and L-serylglycine), and salicylaldehyde. The compounds are characterised and the nature of their coordination spheres shown by analysis, TLC, by appropriate spectroscopy (EPR...

A nickel(II) com plex with (bbim ae) ( — 2-[bis(benzimidazol-2-ylmethyl)amino]ethanol), [Ni(bbim ae)(NCS)2] • FLO (1) and an oxovanadium (IV) complex, [VO (bbim ae)(NCS)2] -dma (dma = N,N-dim ethylacetam ide) (2) have been prepared and their crystal structures determined by X-ray diffraction. Crystal data for 1 at 293 K: a = 13.334(2), b — 17.048(2), c = 10.3829(9) Ä , space group P 2 ,2 ,21, Z...

A large number of studies has been published proposing a range of vanadium containing compounds as potential new anti-diabetic drugs due to the observed insulin mimetic function of V(IV) complexes. Vanadium uptake and distribution within the body have been investigated in animal models by determination of total vanadium concentrations. Phase I and phase IIa human clinical trials have been compl...
