摘要 硝酸镉、双氰胺钠(Na Dca)以及N,N–二甲基乙二胺(Dmda)在水溶液中混合反应得到一个新型配位聚合物[Cd(Dca)2(Dmda)](1).单晶结构分析表明该配位聚合物结晶于P21/c空间群,晶胞参数a=7.446 5(2),b=14.028 3(5),c=12.365 2(4),β=91.476(1)°.该配位聚合物中镉离子通过两种晶体学独立的双氰胺配体的双端配位作用形成了一维双链状结构.进一步地,通过这种双链状结构单元的链内氢键作用以及相邻链单元之间的氢键作用,堆积组装形成了一个结构相对紧凑的三维超分子结构.荧光测试表明,该配位聚合物的荧光发射主要来自于双氰胺配体内部的跃迁. The reaction of cadmium nitrate, sodium dicyandiamide and N, N-dimethyl-ethylenediamine in aqueous solution afforded a new coordination polymer, namely [ Cd(Dca)2 (Dmda)] (1). The X-ray diffraction analysis revealed that 1 crystallizes in the cen- trosymmetric space group P21/c with the following cell parameters: a = 7. 446 5(2)A,b = 14. 028 3(5)A, c = 12. 365 2(4),A,/3 = 91. 476(1) A. In 1 the Cd2+ ions are interconnected via two types of dieyandiamide ligands to form a one-dimensional double-chain structure. These double-chains are further assembled through intra- and inter-chain hydrogen bonds to form a somewhat compact three- dimensional supramolecular structure. The photoluminescenee analysis shows that I exhibits a broad blue fluorescence emission band at 412 nm.
