通过水热方法,采用H3CAM (H3C AM=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.

A cadmium(H) 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(lⅡ) 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.
