ABSTRACT Monomeric six coordinated adducts of 1,5-disubstituted bis(acetylacetonato)oxovanadium(IV) having general formula, [VO(RCOCH2COR’)2(L)], [R= phenyl, CF3R’= Napthyl,CF3 and L= 4-Methyl pyridine, 3-Amino-4-Hydroxy pyridine] have been synthesized and their adducts with 4-Methyl pyridine & 3-Amino-4-Hydroxy pyridine prepared. The compounds were characterized by magnetic moment and molar conduct studies, Mass Spectroscopy, Infra red spectroscopy, electronic spectroscopy, ESR Spectroscopy, Powder X-ray diffraction, magnetic and conductivity measurements having 1:1 stochiometry. The adducts were found to be paramagnetic and their magnetic moments at room temperature lie within the 1.68-1.79 B.M. range and this indicates the presence of one unpaired electron. The values are in accordance with the octahedral geometry. The magnetic moment measurements and electronic spectra illustrates a octahedral geometry around the vanadium centre.
