Thaker, B. T. published the artcileLigating behaviour of Schiff base ligands derived from heterocyclic β-diketone and ethanol- or propanol-amine with oxovanadium(IV) metal ion, SDS of cas: 14580-22-4, the publication is Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (2009), 74A(5), 1016-1024, database is CAplus and MEDLINE.
Synthesis and evaluation of six new oxovanadium(IV) complexes, formed by the interaction of vanadyl sulfate pentahydrate and the Schiff base, viz.; (HL1)-(HL3) and (HL4)-(HL6) such as 5-hydroxy-3-methyl-1-(2-chlorophenyl)-1H-pyrazolone-4-carbaldehyde (I), 5-hydroxy-3-methyl-1-(3-chlorophenyl)-1H-pyrazolone-4-carbaldehyde (II) and 5-hydroxy-3-methyl-1-(3-aminosulfonylphenyl)-1H-pyrazolone-4-carbaldehyde (III) with ethanolamine and propanolamine, resp., in aqueous ethanol medium, are reported. The ligands and their Schiff base ligands were characterized by elemental analyses, IR and 1H NMR. The resulting complexes were characterized by elemental analyses, IR, 1H NMR, mass, electronic, ESR spectra, magnetic susceptibility measurements, molar conductance and thermal studies. The IR spectral data suggest that the ligand behaves as a dibasic bidentate with ON donor sequence towards metal ion. The molar conductivity data show them to be nonelectrolytes. The electronic, magnetic and ESR spectral data suggest that all the oxovanadium(IV) complexes have distorted octahedral geometry.
