A new tetranuclear copper(II) compound containing dissymmetrical oxamidate ligand was synthesized and structurally characterized by IR spectroscopy, elemental analysis, single-crystal X-ray diffraction, and magnetic properties. The title compound 1 crystallizes in triclinic, space group P_1~- with a = 8.9547(9), b = 11.7018(9), c = 12.0288(10), α = 110.1790(10), β = 100.0700(10), γ = 100.6780(10)°, V = 1122.97(17) ~3, C_(34)H_(48)C_(l2)Cu_4N_(10)O_(16), M_r = 1177.92, D_c = 1.742 g/cm~3, μ(MoKα) = 2.067 mm~(-1), F(000) = 600, Z = 1, the final R = 0.0391 and wR = 0.1073 for 3904 observed reflections (I > 2σ(I)). In the structure, complex 1 consists of a tetranuclear unit and two perchlorate anions. Furthermore, its magnetic properties have also been investigated.
