Synthesis,Crystal Structure and Luminescent Properties of Coordination Polymer [{NaCd4(IDC)3(prz)}·3H2O]n with 1D Channels
【摘要】 通过水热方法,采用H3IDC(H3IDC=imidazole-4,5-dicarboxylicacid)、prz(prz=piperazine)与Cd(NO3)2·4H2O反应,合成了具有一维孔道的配位聚合物[{NaCd4(IDC)3(prz)}·3H2O]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化合物属于单斜晶系,Cc空间群。其结构单元中含有4个独立的Cd原子。3个Cd原子形成一个小环,6个Cd原子形成一个大环。这些环通过IDC3-和Cd(Ⅱ)的配位作用,进一步连接产生了含一维孔道的配位聚合物。孔道内含有大量水分子和Na+离子。研究表明,该配合物在室温下能发出很强的兰色荧光。
【Abstract】 A 3D coordination polymer with 1D channels of [{NaCd4(IDC)3(prz)}·3H2O]n(1)(H3IDC=imidazole-4,5-dicarboxylic acid,prz =piperazine) was hydrothermally synthesized,and characterized by single-crystal X-ray diffraction.The crystal belongs to monoclinic system,space group Cc.There are four crystallographically independent Cd(Ⅱ) ions in the crystal lattice.Three Cd(Ⅱ) atoms form a small ring,and six Cd(Ⅱ) atoms form a large ring.The rings are further connected by the coordination interactions of IDC3-and Cd(Ⅱ) to generate a novel 3D frameworks containing 1D hexagonal channels,which is occupied by water molecules and Na+ ions.The compound displays strong blue fluorescent emission at room temperature.CCDC:688709.
