| 摘要: 通过水热方法，采用H3pimda(2-propyl-1H-imidazole-4，5-dicarboxylic acid)与CdSO4·8/3H2O和Nd2O3反应，合成了1个具有一维孔道的配位聚合物[Cd(H2pimda)2]n (1)，并对其结构和荧光性质进行了研究。结构分析结果表明该聚合物的晶体属于单斜晶系，P21/n空间群。4个H2pimda-配体桥联4个镉(Ⅱ)离子形成了1个方环，这些环通过镉(Ⅱ)离子与H2pimda-配体的配位作用形成了1个具有一维孔道的三维框架结构。值得关注的是配合物1的晶体呈现一种微米管的外型。研究表明，该聚合物中在室温下能发出很强的兰色荧光。 |

| Abstract: Under hydrothermal conditions, CdSO4·8/3H2O reacts with 2-propyl-1H-imidazole-4,5-dicarboxylic acid (H3pimda), in the presence of Nd2O3, producing a novel coordination polymer [Cd(H2pimda)2]n (1). Complex 1 crystallizes in monoclinic space group P21/n, with a=0.823 50(3), b=1.070 54(5), c=1.118 50(5) nm, β=90.082(2)°, V=0.986 06(7) nm3, and Z=2. Single-crystal X-ray diffraction studies show that complex 1 has a 3D open coordination framework with 1D channels. It is worth noting that microscopic single-crystal tubes were assembled with compound 1. Luminescent properties of compound 1 has also been studied. CCDC: 849059. |
