Synthesis, Characterization and 3-D Molecular Modeling of Some Oxovanadium(IV) Complexes Involving O

چکیده
Vanadium plays an important role in life and one of its most relevant properties identified is its capacity to act as insulin-enhancing agent, either in the form of its inorganic salts or complexes with organic ligands. Besides the antidiabetic action, vanadium complexes are known to possess potent anticancer activity, which deserve increasing attention for application to biomedical sciences. Synthesis and studies of Vanadium complexes have induced a considerable amount of interest due to their application as important catalysts in several chemical reactions. In view of the wide application of Vanadium complexes, a series of oxovanadium(IV) complexes involving pyrazolone-based aroylhydrazone and 8-hydroxyquinoline have been synthesized and characterized by different physicochemical studies such as elemental analysis, molar conductance, magnetic measurements, infrared, TGA, ESR, mass and electronic spectral studies. The overall experimental data based from all the studies presented suggests the complexes under present investigation are of the general composition [VO(L)(8-hq)(H 2 O)], where LH= pyrazolonebased aroylhydrazone and 8-hqH= 8-hydroxyquinoline, involving a monobasic didentate (O,N) donor ligand. An octahedral structure with axial oxo groups have been proposed for these complexes.
