【Abstract】 Two mononuclear complex [(trien)Cu](ClO4)2, [(trien)Cu imH](ClO4)2 and one Cu(Ⅱ)-Zn(Ⅱ) asymmetric heterobinuclear complex bridged by imidazolate [(trien)Cu im Zn(tren)](ClO4)3(Where trien = triethylenetetraamine, tren = 2,2’,2"- triaminotriethylamine, im = imidazolate anion) were synthesized and characterized by elemental analysis, molar conductivity, spectra of reflectance and magnetic moments at room temperature. The electrochemical properties of complexes were respectively examined by cyclic voltammetry in CH3CN and in H2O. The results show that the presence of Zn(Ⅱ) increase the electron accepting ability of Cu(Ⅱ) in the imidazolate-bridged Cu(Ⅱ)-Zn(Ⅱ) complexes. Furthermore, the experimental data indicated that all of the imidazolate bridge split at Zn(Ⅱ) side in water solution.更多还原
