Cu(Ⅱ)-Co(Ⅱ) heterobinuclear complex was synthesized from an oxalamide bridged macrocyclic dioxotetraamines and characterized by IR, UV-visible spectra, molar conductivity, thermogravity analysis, cyclic voltammetry and room temperature magetic moment measurements. The results suggested the Cu(Ⅱ)-Co(Ⅱ) heterobinuclear complex has an oxalamide brideged structure with copper(Ⅱ) being in a planar and cobalt(Ⅱ) in an octahedral environment. Room temperature magetic studies showed that there are weak antiferromagetic interactions between the two metal ions within a molecule. Cyclic voltammetry studies showed this complex can stabilize higher oxidation states of Cu(Ⅲ). Mononuclear Cu(Ⅱ) complex is of monoclinic system, space group P2_1/c, a=0.7386 1(15) nm, b=2.121 1(4) nm, c=0.952 50(19) nm, U=94.70(3)° and Z=4. Fall-matrix least-squares refinement of the structure led to a conventional weighted R factor of 0.051 3.
