摘要：

[LCu{mu-(OH)(2)(C2O2)}CuL](ClO4)(2), (HL = N,N-dimethyl N-propylsalicylald-imine) was synthesised and its crystal structure was determined. C26H36Cl2Cu2N4O14, triclinic space group P (1) over bar with a = 9.288(9), b = 10.016(11), c = 10.09(2) Angstrom and alpha = 101.05(11), beta = 108.22(10), gamma = 110.22(10)degrees, V = 787(2) Angstrom(3), Z = 2. Two copper(II) ions in a distorted square-planar coordination are bridged by an oxalic acid molecule to form dinuclear units. The copper(II) centres are separated by 5.2 Angstrom and antiferromagnetically coupled (J = -478 cm(-1)), which follows from temperature-dependent magnetic susceptibility measurements in the range 12 to 300 K.
