| 摘要: 以4-（1H-1，2，4-三氮唑）苯甲酸为配体，采用水热法合成了2种稀土配位聚合物[Tb（tbc 3）（H2O）3]n（1）和{[Nd（tbc3）（H2O）3]·H2O}n（2）（Htbc=4-（1H-1，2，4-三氮唑）苯甲酸）.运用X-射线单晶衍射法对该配位聚合物进行了结构测定，并对其进行了元素分析、红外光谱、TG及荧光光谱表征。单晶结构表明，配位聚合物1为三斜晶系，空间群P1，配位聚合物2属于单斜晶系，空间群为P21/c.配位聚合物1和2均为一维链结构，均通过非共价键作用形成三维超分子构造。 |

| Abstract: Two lanthanide Coordination Polymers, [Tb(tbc3)(H2O)3]n 1) and {[Nd(tbc3)(H2O)3]·H2O}n (2) [Htbc=4-(1H-1,2,3-triazol-1-yl) benzoic acid], have been synthesized by hydrothermal method and structurally characterized by elemental analyses, FT-IR spectra, and thermal studies, fluorescence spectra, as well as single crystal X-ray diffraction. Structural determination reveals that complex 1 belongs to triclinic system and space group P1. And complex 2 crystallizes in monoclinic system, space group P21/c. Both 1 and 2 possess a one dimensional chain structure constructed from carboxylate O atoms of Htbc ligand bridging the units. Through non-covalent interactions the complex molecules are assembled into 3D supramolecular network structures.CCDC: 957286, 1; 957287, 2. |
