Roy, Sutapa published the artcileSynthesis, characterization and 3-D molecular modeling of some oxovanadium(IV) complexes involving O2N2 donor core, SDS of cas: 4551-69-3, the publication is Journal of Pharmacy and Chemistry (2014), 8(4), 9-13, database is CAplus.
In view of the wide application of vanadium complexes, oxovanadium(IV) complexes involving pyrazolone-based aroylhydrazone and 8-hydroxyquinoline were synthesized and characterized by different physicochem. studies such as elemental anal., molar conductance, magnetic measurements, IR, TGA, ESR, mass and electronic spectral studies. The overall exptl. data based from all the studies presented suggests the complexes under present investigation are [VO(L)(8-hq)(H2O)], where LH- pyrazolone-based aroylhydrazone and 8-hqH = 8-hydroxyquinoline, involving a monobasic didentate (O,N) donor ligand. An octahedral structure with axial oxo groups are proposed for these complexes.
