Abstract

Abstract: Complex VO(C₁₂H₁₂N2O₂)(C₁₃H₁₀NO₂)(C₁₂H₁₂N₂O₂^2-=acetylacetone benzoylhydrozanate, C₁₃H₁₀NO₂^-=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 P2₁/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) nm³, 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 CH₂Cl₂<CH₃CN<DMF.

Key words: Oxovanadium(Ⅴ) hydrazone complex, Hydroxamate complex, Crystal structure, Spectral property
