| 摘要: 以三（4-咪唑基苯基）胺（TIPA）和碘化镉为原料，分别与环已二酸（H2CDC）和5-甲基间苯二甲酸（H2MPDA）在水热条件下反应，得到2个结构不同的配位聚合物[CdI（TIPA）（CDC）0.5]n（1）和{[Cd（TIPA）（MPDA）]·H2O}n（2）。对它们进行了元素分析、红外光谱分析，并利用X射线衍射测定了它们的单晶结构。单晶结构分析显示，配合物1拥有二维两重贯穿的（3，4）-连接的（4.52）（4.53.72）拓扑结构，层与层之间通过弱相互作用连接成三维超分子结构；而配合物2具有二维（3，5）-连接的（42.67.8）（42.6）拓扑的层状结构，层与层之间通过互锁方式连接成三维金属有机骨架。结果说明了有机羧酸在配合物组装过程中起着非常重要的作用。此外，在室温下对2个配合物进行了荧光性质分析。 |

| Abstract: Two cadmium(Ⅱ) coordination polymers,[CdI(TIPA)(CDC)0.5]n (1) and {[Cd(TIPA)(MPDA)]·H2O}n (2), (TIPA=tris(4-imidazolylphenyl)amine, H2CDC=1,4-cyclohexanedicarboxylic acid, H2MPDA=5-methylisophthalic acid), have been synthesized and characterized by IR spectroscopy, elemental analyses and single-crystal X-ray diffraction. Structural analyses reveal that complex 1 features a rare 2D→2D polyrotaxane network with (3,4)-connected (4.52)(4.53.72) topology, which is further interlinked into a higher-dimensional supramolecular framework by intermolecular weak interactions, whereas complex 2 has a two-dimensional (3,5)-connected novel network with (42.67.8)(42.6) topology and shows a 2D→3D parallel-parallel polycatenation framework. The results show that the carboxylates exert obvious influence on the resulting architectures. Meanwhile, the solid-state photoluminescence of two complexes at room temperature was also investigated. |
