A Cu () -Co () heterobinuclear complex with an oxalamide bridged macrocyclic dicarbonamide structure was synthesized and characterized by FTIR, electronic spectroscopy, molar conductance, thermogravimetry, magnetic moment at room temperature, cyclic voltammetry Etc. It was preliminarily assumed that the Cu () -Co () heterobinuclear complex had an oxalamide bridged macrocyclic dinitrotetra amine structure.The magnetic moment measurements at room temperature showed that the Cu Some anti-ferromagnetic spin coupling effect.Cyclic voltammetry was measured by the half-wave potential of the complex, the experimental results show that such complexes can stabilize the high valence Cu () ) Ion has no effect on the redox process.Under the X-ray crystallography of mononuclear complex, it is monoclinic with space group P2 1 / c, a = 0.73 861 (1 5) nm, b = 2. 1 2 1 1 (4) nm, c = 0.95 2 5 0 (1 9) nm, β = 94.70 (3) °, R1 = 0 .0 5 1 3, w R2 = 0.1 1 77, Z = 4.Cu () is macrocyclic tetramine above the center of the plane 0. 0 3 nm, and has a protracted oxamide bridge
