摘要: 以一种尿素的衍生物2-咪唑烷酮为溶剂,采用脲热法合成了一个新的配位聚合物[Cd(NH₂bdc)(e-urea)]_n(1)(H₂NH₂bdc为2-氨基对苯二甲酸,e-urea为2-咪唑烷酮),并对其结构和荧光性质进行了研究。单晶结构分析结果表明,标题化合物的中心镉(Ⅱ)离子分别与2-氨基对苯二甲酸根配体的羧基氧原子和溶剂氧原子配位形成七配位的变形五角双锥结构。相邻的中心镉(Ⅱ)离子通过溶剂氧原子和配体羧基基团的连接,形成无限的一维链。这些一维的链进一步通过2-氨基对苯二甲酸根配体的连接最终形成了具有一维孔道的三维框架结构。研究表明,该化合物在室温下能发出较强的蓝色荧光。

Abstract: Anew coordination polymer, namely [Cd(NH₂bdc)(e-urea)]_n (1) (H₂NH₂bdc=2-amino^-1,4-benzenedicar-boxylic acid, e-urea=2-imidazolidinone) has been urothermally synthesized by using urea derivative 2-imidazoli-dinone as solvent and its structure and fluorescence property have also been investigated. The crystallography analysis reveals that the centric Cd(Ⅱ) ion is seven coordinated by carboxylate oxygen atoms from NH₂bdc ligands and oxygen atoms of e-urea molecules forming a distorted pentagonal-bipyramidal coordination geometry. The adjacent Cd(Ⅱ) centers are bridged by oxygen atoms of e-urea molecules and carboxylate groups of NH₂bdc ligands forming an infinite 1Dchain. Thus 1Dchains are further connected together by NH₂bdc ligands into a 3D coordination framework with 1D tunnels. Luminescent study shows that complex 1 displays a strong blue emission at room temperature. CCDC: 902023.
