Heterobinuclear complex CuVOTS·MeOH, where TS is the schiff base N,N'-bis(3-carboxylsalicylidene)trimethylenediamine, was synthesized and characterized by elemental analysis, IR and UV-vis spectra. The electrochemical property of the complex was examined by cyclic voltammetry in DMSO. The results show that the coordination of the second metal ion could increase the stability of the inner copper(Ⅱ) ion. The temperature dependence of the magnetic susceptibility of Cu(Ⅱ)-VO(Ⅱ) over the range 4~300 K gave the exchange integral J=-1.631 2 cm^-1, which indicates the presence of weak antiferromagnetic interaction between the internal Cu²⁺ ion and the outer VO²⁺ ion in the heterobinuclear complex.
