The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.

The condensation of isatin with pyridine carboxylic acid hydrazides in methanol give rise to hydrazone ligands. By the reactions of oxovanadium(IV) sulphate with hydrazones in presence of sodium hydroxide in methanol [VO(L)H2O] type complexes were obtained. The complexes were characterized by elemental analyses, conductances, magnetic moments, TGA and spectral (IR, Electronic and EPR) data. The...

There is an urgent medical need for orally effective drugs to replace insulin injections for the treatment of diabetes mellitus. Vanadium complexes with insulin-mimetic activities have recently been proposed as candidates as new antidiabetic drugs. Following in vitro and in vivo studies on a group of bis(3-hydroxy-4-pyronato)oxovanadium(IV) (1) complexes with VO(O4) coordination mode, bis(allix...

Two new tetradentate oxovanadium(IV) and iron(II) Schiff base complexes have been prepared by the interaction of vanadyl(IV) iron(III) acetylacetonate with ligand obtained from reaction ethylenediamine 5?-(N-methyl-N-phenylaminomethyl)-2?-hydroxyacetophenone in methanol. These characterized means different spectroscopic techniques such as UV–visible, FT-IR, mass spectrometry, elemental analysis...

Five oxovanadium(IV) complexes, which were divided into two groups, [V(IV)O(bhbb, nhbb)(H(2)O)(2)] (tridentate ligands: H(2)bhbb = 2-(5-bromo-2-hydroxylbenzylideneamino)benzoic acid, 1; H(2)nhbb = 2-(5-nitro-2-hydroxylbenzylideneamino)benzoic acid, 2) and [V(IV)O(cpmp, bpmp, npmp)(2)] (bidentate ligands: Hcpmp = 4-chloro-2-((phenylimino)methyl)phenol, 3; Hbpmp = 4-bromo-2-((phenylimino)methyl)p...
