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<CH\-3CN<DMF.
