摘要：

A new dinuclear complex, [Cu-2(TPA)(2)(o-phth)](ClO4)(2) (TPA = tris(2-pyridylmethyl) amine, o-phth = terephthalato dianion), was synthesized and characterized by X-ray crystallography. The unit of dinuclear Cu(II) was bridged by terephthalato dianion. The complex crystallizes in triclinic space group P (1) over bar, with a = 8.287(3) angstrom, b = 10.623(4) angstrom, c = 13.818(5) angstrom; alpha = 92.077(7)degrees, beta = 94.768(7)degrees, gamma = 90.352(6)degrees; V = 1211.4(8) angstrom(3); Z = 2; R-1 = 0.0604, wR(2) = 0.1707. In the temperature range 4-300 K, magnetic measurement shows that the exchange interaction of the two metal ions is weak ferromagnetic with J = 1.20 cm(-1), g = 1.97.
