本文报道了两个新的由羧酸根取代的苯并咪唑和甲酸根配体形成的配位聚合物：[Mn（L）·（HCO_2）]_n（1）和[Co（L）·（HCO_2）]_n（2）（L =苯并咪唑-1-乙酸酯）。配合物1和2是同构的，并采用一种新的3，6-连接的三节点拓扑结构，显示出有趣的磁性：Mn Ⅱ配合物1的自旋倾斜反铁磁性，但Co Ⅱ配合物2的简单反铁磁性耦合。
This paper reports two new coordination polymers formed by carboxylate-substituted benzoimidazole and formate ligands: [Mn(L)·(HCO2)]n(1) and [Co(L)·(HCO2)]n(2) (L = benzoimidazol-1-yl-acetate). Complexes 1 and 2 are isomorphous and adopt a new 3,6-connected three-nodal topology showing interesting magnetic properties: spin canted antiferromagnetism for MnIIcomplex 1, but simple antiferromagnetic coupling for CoIIcomplex 2.
