Monomeric six coordinated adducts of bis(acetylacetonato)oxovanadium(IV) having general formula, [VO(acac)2(L)], [L= pyrrolidine, morpholine, 2,4,6-trimethylpyridine, 2,4, 2,6, 3,4, 3,5-dimethylpyridines, 2-ethylpyridine, 2-methylpyridine, 3-methylpyridine 2, 3, 4-cyanopyridine, quinoline, isoquinoline] have been synthesized and characterized by elemental analysis, IR, electronic spectroscopy, magnetic and conductivity measurements having 1:1 stoichiometry. The adducts were found to be paramagnetic and their magnetic moments at room temperature lie within the 1.72-1.87 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 depicts a octahedral geometry around the vanadium center. The investigated adducts have also tested against the fungus Fusarium oxysporum.
