A new oxido-vanadium(V) complex, [VO(L)(PrOH)(OPr)] (L = [(3-methoxy-2oxidobenzylidene)benzohydrazidato], PrOH = propanol, OPr = propanolato) has been synthesized and characterized by means of elemental analysis, Fourier transform infrared (FTIR), proton nuclear magnetic resonance (1HNMR), ultaviolet-visible (UV?Vis) spectroscopy, voltammetry and molar conductivity measurement. The structure of the complex has also determined using single crystal X-ray diffraction. The geometric structure around the V(V) ion has been found to be octahedral in which the positions around the central ion are occupied by ONO ligand donors, oxido groups, and oxygen atoms of coordinated propanol and propoxide group. Electrochemical behavior of this complex is also discussed in more details.
