摘要：
A new oxamido-bridged trinuclear copper(II) complex [(CuL)(2)Cu](ClO4)(2)center dot 0.5H(2)O (L=the dianion of 2,3-dioxo-5,6,14,15-dibeiizo-7,13-bis(ethoxycarbonyl)-1,4,8,12-tetraazacyclotetradeca-7,12-diene) has been synthesized by self-assembly and characterized. X-ray diffraction analysis reveals that the title complex is monoclinic, space group P2(1), with a = 16.213(5), b = 9.811(3), c = 18.802(6) angstrom, beta = 96.790(5)degrees. The central copper(II) ion lies in a distorted octahedral environment. Terminal coppers have square pyramidal coordination geometry. Magnetic measurements show there is strong antiferromagnetic interaction between the central and the terminal Cu(II) ions.
