By using a triazol-functionalized tricarboxylate, three novel metal coordination polymers, namely, [Zn2L(OH)]·0.5H2O (1), [Co2L(OH)(H2O)]·5.5H2O (2), [Cu2(HL)] (3) L = [5-(3-(4-carboxyphenyl)−5-methyl-4H-1,2,4-triazol-4-yl)isophthalate] were synthesized under hydrothermal reactions. All the compounds were characterized by element analysis, IR spectroscopy, thermogravimetric analysis, power X-ray diffrcation and single-crystal X-ray diffrcation. Structural analysis reveals that compounds 1 and 2 have 3D networks with flu topologies where rigid trizaol-functionalized ligands as 4-connected nodes and Zn4(COO)6 or Co4(COO)6 clusters serves as 8-connected secondary building units. Compound 3 has 3D network with pcu topology where Cu4(COO)4 clusters serve as 6-connected secondary building units. Gas adsorption studies reveal that desolvated compoud 1 exhibits high H2 absorption capacity at 77 K and highly selective separation abilities of CO2 and C3H8 over CH4 at room temperature. The results suggest that 1 has potential application in gas storage and separation. In addition, the magnetic properties of compound 2 were also investigated.

基于三唑官能化刚性配体的三种3D金属配位聚合物:合成,拓扑结构和性质

通过使用三唑官能化的三羧酸盐,三种新型金属配位聚合物,即[Zn 2 L(OH)]·0.5H 2 O(1),[Co 2 L(OH)(H 2 O)]·5.5H 2 O(2 [Cu 2(HL)](3)L = [5-(3-(4-羧基苯基)-5-甲基-4H-1,2,4-三唑-4-基)间苯二甲酸酯]在水热反应下合成。所有化合物均通过元素分析,红外光谱,热重分析,功率X射线衍射和单晶X射线衍射进行了表征。结构分析表明,化合物12具有3D网络,流感拓扑结构,其中刚性三唑官能化配体作为4个连接节点,而Zn 4(COO)6或Co 4(COO)6簇用作8个连接的二级建筑单元。化合物3具有带有pcu拓扑的3D网络,其中Cu 4(COO)4簇用作6个连接的辅助建筑单元。气体吸附研究表明,去溶剂化的化合物1在77 K时具有很高的H 2吸收能力, 并且在CH 4之上具有高选择性的CO 2和C 3 H 8分离能力。在室温下。结果表明1在气体的存储和分离方面具有潜在的应用前景。另外,还研究了化合物2的磁性能。
