| 摘要: 通过水热方法，采用H3CAM(H3CAM=4-hydroxy-pyridine-2，6-dicarboxylic acid)与Cd(NO3)2·4H2O反应，合成了1个镉配位聚合物[Cd4(HCAM)4(H2O)8]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配合物属于单斜晶系，C2/c空间群。四个HCAM2-配体桥联4个镉离子形成了1个四核镉单元。这些孤立的单元通过氢键作用形成了1个三维配位框架。研究表明，该配合物在室温下能发出兰色荧光。 |

| Abstract: A cadmium(Ⅱ) complex of [Cd4(HCAM)4(H2O)8]n (H3CAM=4-hydroxy-pyridine-2,6-dicarboxylic acid) (1) has been synthesized under hydrothermal condition and characterized by elemental analysis, IR spectroscopy, TG analysis, and luminescent analysis. Single-crystal X-ray diffraction analyses reveal that complex 1 has a tetranuclear unit with four cadmium ions bridged by four HCAM2- ligands. The Cd(Ⅱ) complex belongs to monoclinic system, with space group C2/c, a=1.754 77(4) nm, b=1.293 47(4) nm, c=1.652 25(4) nm, β=100.714(2)°, V=3.684 81(17) nm3, Z=4, R1=0.024 4, wR2=0.058 1. The discrete tetranuclear units are further assembled into a 3D supramolecular framework through H-bond interactions. In the solid state, complex 1 shows blue emission at room temperature. CCDC: 794674. |
