The preparation and characterization of a new oxalato-bridged dinuclear CuⅡ complex, [Cu2(L)2(μ-ox)](ClO4)2 (1), where L=1,5,9-triazacyclododecane, together with its spectral and magnetic properties are reported. The magnetic susceptibility of 1 indicates a very strong anti-ferromagnetic coupling with 2J=-454 cm-1. The strength of the exchange interaction is discussed in detail.%报道了一个新型草酸根桥联双核铜(Ⅱ)配合物[Cu2(L)2(μ-ox)](ClO4)2 (1)(L=1,5,9-三氮环十二烷)的制备、表征、光谱和磁性质.配合物1中的2个铜离子之间存在非常强的反铁磁耦合作用(2J=-454 cm-1).
