Complex VO(C-{12}H-{12}N-2O-2)(C-{13}H-{10}NO-2)(C-{12}H-{12}N-2O+{{}+{2-}}-2=acetylacetone benzoylhydrozanate,C-{13}H-{10}NO+_-2=%N%|phenylbenzohydroxamate) was synthesized and characterized by means of elemental analysis,IR and UV spectroscopies,cyclic voltammetry and single crystal X|ray diffraction. The complex crystallized in the monoclinic system with space group %P%2-1/%n% and the crystal cell parameters %a%=1^3003(1) nm,%b%=0^88836(6) nm,%c%=2^0196(2) nm,%β%=95^065(8)°,%V%=2^3238(3) nm+3,%M%-r=495^40 and %Z%=4. The two oxygen and one nitrogen atoms of the tridentate hydrazone ligand coordinate to the vanadium atom,forming an equatorial plane. And the coordinated vanadium atom exhibits a distorted octahedral geometry. The atom in the transposition to the oxo O atom is the carbonyl oxygen atom of the hydroxamate ligand in the complex. The half|wave redox potential of the title complex in the three different solvents positively shifts in the order of CH-2Cl-2
