| Abstract: | The complex VO(L) (CH3O) (CH3OH) (H2L=salicylaldehyde benzoylhydrazone) was synthesized and characterized by elemental anlyasis, IR, UV, 1H NMR, cyclic voltammetry measurements and X-ray diffraction. The crystal belongs to monoclinic system, space group P21/c, with the crystal cell dimensions a=0. 8161(1) nm, b=1. 6946(2) nm, c=1. 2232(1) nm, β=104. 274(9)°, V=1. 6394(3) nm3, Mr=368. 26, Z=4. Two oxygen atoms and one nitrogen atom of the tridentate hydrazone ligand are coordinated to vanadium(V) atom, forming an equatorial plane. The vanadium atom approximates to a distorted octahedral coordination sphere. The redox potentials of the title complex in different solvents follow the order: CH2Cl23CN
