Abstract: The non-oxovanadium(IV) complexes of composition [VCl2-n(acac)2(OAr)n] and [VCl₂₋ո(acac)₂(OAr')ո] [(OAr = ⁻OC₆H₄C₆H₅-2; OAr' = ⁻ OC₆H₄C₆H₅-4; acac = acetylacetonate ion (CH₃COCHCOCH₃⁻); n = 1 and 2)] have been synthesized by the reaction of [VCl₂(acac)₂] with the sodium salt of the respective phenols. The complexes have been characterized by elemental analyses, molar conductance measurements, molecular weight determinations and infra-red, electronic and FAB-MS spectral and magnetic moment studies. The room temperature magnetic moments of the complexes lying in the range 1.71-1.79 μ B conform to vanadium (IV) oxidation state. Based upon these studies, monomeric distorted octahedral structures for the complexes have been proposed. The reactions of [VCl(acac)₂ (OAr)] and [VCl(acac)₂(OAr')] with sodium alkoxides, NaOR (OR = OMe and OEt) afforded ternary complexes of type, [V(OR)(acac)₂(OAr)] and [VOR(acac)₂(OAr')], authenticated by physicochemical and infrared spectral studies.
