摘　　要：通过扩散法合成了一个新的配位聚合物{[Cu2(OH)(btre)1.5(1,2,4-btc)]·13H2O}n(1·13H2O)(btre=1,2-二(4H-1,2,4-三唑)乙烷,1,2,4-btc=1,2,4-苯三甲酸根)。测试了1·13H2O的晶体结构,并用红外光谱、元素分析、粉末X射线衍射对其进行表征。单晶X射线衍射表明1是基于四核铜簇[Cu4(μ2-OH)2N12]构筑的10-连接的3D框架,其拓扑符号为312·428·55。研究了1·13H2O的热稳定性以及对甲基橙的催化降解作用。One new coordination polymer,{[Cu2(OH)(btre)1.5(1,2,4-btc)]·13H2O}n(1·13H2O)(btre=1,2-bis(4H-1,2,4-triazole)ethane,1,2,4-btc=1,2,4-benzenetricarboxylate),was synthesized under room temperature condition and characterized by single-crystal X-ray diffraction,elemental analyses,IR spectroscopy and powder X-ray diffraction.Sing-crystal X-ray structural analysis shows that compound 1 features a 3D framework based on the tetranuclear[Cu4(μ2-OH)2N12].The 3D coordination network of 1 is a 10-connected network with(312·428·55)topology based on the tetranuclear copper cluster nodes.The thermogravimetric(TG)analysis and photocatalytic degradation of methyl or-ange(MO)of 1·13H2O were studied.CCDC:1526760.
