Five new coordination polymers based on a new 2,2'-bipyridine derived ligand N,N'-bis(pyridin-4-yl)-2,2'-bipyridine-5,5'-dicarboxamide (=L) are reported herein. Isostructural three-dimensional coordination polymers with a rare (4,6)-connected network of {4(4).6(2)}(3){4(6).8(9)}(2) topology were synthesised from Cu(NO(3))(2), Zn(NO(3))(2) or a mixture of Cu(NO(3))(2)/Fe(BF(4))(2) with L in complexes {[Cu(5)L(6)]·(NO(3))(10)·(H(2)O)(18)}(∞) (1), {[Zn(5)L(6)]·(NO(3))(10)·(H(2)O)(18)}(∞) (2) and {[Fe(x)Cu(y)L(6)]·(NO(3))(10)·(H(2)O)(18)}(∞) (3; where x+y=5). Complexes with two-dimensional grid structures resulted from treatment with CoCl(2) or Cd(NO(3))(2) with L in complexes {[CoLCl(2)]·DMF}(∞) (4) and {CdL(NO(3))(2)}(∞) (5).
本文报道了五种基于新的 2,2'-联吡啶衍生配体 N,N'-双（吡啶-4-基）-2,2'-联吡啶-5,5'-二甲酰胺（=L）的新型配位聚合物。通过 Cu(NO3)2、Zn(NO3)2 或 Cu(NO3)2/Fe(BF4)2 的混合物与 L 在配合物 Cu5L610(H2O)18](∞)（1）、Zn5L610(H2O)18](∞)（2）和 Fe(x)Cu(y)L610(H2O)18](∞)（3 中合成了具有罕见（4,6）连接网络的三维配位聚合物，其中 x+y=5）。与 CoCl2 或 Cd(NO3)2 处理时，与 L 在配合物 CoLCl2∞（4）和 CdL(NO3)2](∞)（5）中得到了二维网格结构的配合物。
