The heterodinuclear complex [LCuIIVIVO] 1 was synthesized by using a new unsymmetric dinucleating ligand based on 1,8-naphthalenediol, whereas the homodinuclear CuIICuII complex 2 has a bridging beta-diketimineamid unit. Here we report on the synthesis, molecular structures, and magnetic properties of 1 and 2. In the solid state, both complexes dimerize to tetranuclear entities 1(2) and 2(2). The intradimer interaction in both complexes is ferromagnetic because of the orthogonality of the magnetic orbitals (J12 = +45.6 cm(-1) in 1 and +4.8 cm(-1) in 2). The interdimer interaction in 1 is also ferromagnetic, giving a St = 2 ground state.
通过使用一种基于1,8 - 萘二醇的新型不对称双核配体合成了异双核配合物[LCuIIVIVO] 1，而同双核CuIICuII配合物2具有一个桥连的β - 二酮亚胺酰胺单元。在此我们报道1和2的合成、分子结构及磁性。在固态下，两种配合物均二聚形成四核实体1(2)和2(2)。由于磁轨道的正交性，两种配合物中二聚体内的相互作用都是铁磁性的（1中J12 = +45.6 cm(-1)，2中J12 = +4.8 cm(-1)）。1中三聚体间的相互作用也是铁磁性的，基态为St = 2。
