Microwave-assisted synthesis is a branch of green chemistry. The salient features of microwave approach are shorter reaction times, simple reaction conditions and enhancements in yields. Vanadium containing compounds have their utility in various physicochemicals, biochemical physiological, enzymatic and catalytic processes. Novel six binary/mixed ligand oxovanadium(IV) complexes [VO(deb)(H2O)](I), [VO(deb)(hq)(H2O)](II), [VO(dpeda) 2].SO4.H2O(III), [VO(dndsa)(H2O) 2].SO4.3H2O(IV), [VO(tcne)].(VO3) 2.H2O(V), [VO(dnph) 2(VO3)2].H2O(VI) have been synthesized by conventional as well as microwave methods. These compounds have been characterized by elemental analyses, thermal data, FAB mass, FT-IR, molar conductance, electronic spectra, ESR and magnetic measurements. FAB mass and Thermal data show degradation pattern of the complexes. The thermal behavior of complexes shows that the hydrated complexes lose water molecules of hydration in the first step; followed by decomposition of ligand molecules in the subsequent steps. The reactivity and substitution behaviour of the synthesized complexes have also been studied.
