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.

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1和2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。
