摘要以5，5 ′-二（吡啶-3-基）-3，3 ′-二（1，2，4-三唑）（3，3 ′-H2 dbpt）为氮杂环结构单元，合成了四种不同连接方式的三维配位聚合物[M（3，3 ′-dbpt）]n，M=Co（1），M=Ni（2），M=Zn（3），[Cd 2（3，3 ′-dbpt）Cl 2]n（4）。通过改变中心金属离子，3，3 ′-H2 dbpt具有三种不同的配位模式。因此，同构的1-3具有3-D 4-连通拓扑，具有（42.84）Schläfli符号。4是一个三维（4，6）拓扑，符号为（43.63）2（46.66.83）Schläfli。1和2都表现出弱的反铁磁行为。此外，3和4分别显示紫色和蓝色发射带。这些结果表明，3，3 ′-H2 dbpt是一个很好的多连接连接基团，可以用来构建具有有趣结构和性能的MOFs。
Abstract Using the N-heterocyclic building block 5,5′-di(pyridin-3-yl)-3,3′-bi(1,2,4-triazole) (3,3′-H2dbpt), four 3-D coordination polymers with diverse connectivity, [M(3,3′-dbpt)]n, M=Co (1), M=Ni (2), M=Zn (3), and [Cd2(3,3′-dbpt)Cl2]n (4), were constructed. By changing the central metal ions, 3,3′-H2dbpt had three different coordination modes. Consequently, 1–3, which are isostructural, have a 3-D 4-connected topology with (42.84) Schläfli symbol. 4 has a 3-D (4, 6)-topology, with (43.63)2(46.66.83) Schläfli symbol. Both 1 and 2 reveal weak antiferromagnetic behavior. In addition, 3 and 4 exhibit purple and blue emission bands, respectively. These results indicate that 3,3′-H2dbpt is an excellent multi-connection linker to construct MOFs with interesting structures and properties.
