A novel oxamido-bridged trinuclear complex Cu(NiL)2(ClO4)2 (where H2L=2,3-dioxo-5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,3-dien) has been synthesized and characterized by elemental analysis, IR spectrum, UV-Visible spectrum and single crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P21/n. The lattice parameters are: a=1.052 4(6) nm, b=1.182 1(6) nm, c=1.586 2(9) nm, a=91.657(9) and V=1.972 6(19) nm3, Z=2. The results show that the coordination geometry around copper(Ⅱ) in the title complex is hexa-coordinated octahedron. CCDC: 232608.
