摘要：

A title compound has been synthesized and characterized. The complex crystallizes in the monoclinic space group C2/c with a = 12.768(1)Angstrom, b = 7.5159(8)Angstrom, c = 13.271(1)Angstrom, beta = 123.591(4)degrees, V = 1060.8(2)Angstrom(3) and Z = 4. The complex consists of one-dimensional chains of copper(II) ions bridged by pyrazine-2,3-dicarboxylate. Each copper ion has a distorted octahedral coordination with N2O4 chromophor. The magnetic susceptibility data over a range of 2 - 300 K were fitted by using an Heisenberg antiferromagnet, H = 2J Sigma S-i . Si+1, with the parameters of J = -1.40 cm(-1), g = 2.14 and rho = 0.032.
