【Abstract】 Four novel heterobinuclear complexes have been synthesized, [Cu(oxca)M(phen) 2]ClO 4·2H 2O where oxca=N-(2-carboxy phenyl)-N-(3-aminopropyl) oxamide; phen=1,10-phenanthroline; M=Mn 2+ , Co 2+ , Ni 2+ , Zn 2+ . The results obtained from IR?elemental analysis?thermogravimetric analysis conductivity, electronic spectrum and room temperature magnetic moment measurements showed these complexes appeared to have extended oxamido-bridged structures. The electrochemical properties of the heterobinuclear complexes have been measured by cyclic votammetry in DMSO. The temperature dependence of the magnetic susceptibility of Cu(Ⅱ)-Mn(Ⅱ) and Cu(Ⅱ)-Ni(Ⅱ) over the range 4~300 K gave the exchange integral of J=-10 56 cm -1 and J= -17 08 cm -1 .更多还原
