通过水热合成方法得到了一个基于双核铜簇[Cu2(1,4-bth)3]4+和[β-Mo8O26]4-阴离子的有机-无机杂化化合物,[Cu2(1,4-bth)3(H2O)(β-Mo8O26)] (1)(1,4-bth=4-(6-(1H-1,2,4-三氮唑-1-基)正己烷)-4H-1,2,4-三氮唑),并通过元素分析、红外光谱、X-射线单晶衍射、热分析等测试对其进行了表征.晶体数据表明该化合物属于三斜晶系,P(1)空间群.在化合物1中,1,4-bth配体都以三齿配体的形式与3个铜离子相连,形成双核铜簇[Cu2(1,4-bth)3]4+,每个簇单元进一步和其相邻的4个同类型单元相连形成了相互平行的层状结构[Cu2(1,4-bth)3]n4n+,层与层之间又通过[β-Mo8O26]4-阴离子相连构筑成1个三维框架结构,其拓扑类型为pcu alpha-Po 简单立方格子;热分析表明该化合物具有相对较高的热稳定性.

An organic-inorganic hybrid [Cu2(1,4-bth)3(H2O)(β-Mo8O26)] (1) (1,4-bth＝4-(6-(1H-1,2,4-triazol-1-yl)hexyl)-4H-1,2,4-triazole)) based on dimeric copper clusters [Cu2(1,4-bth)3]4+ and [β-Mo8O26]4-polyanions has been synthesized and characterized by element analysis,IR spectra,single-crystal X-ray diffraction,thermal analysis.The crystallographic data shows that complex 1 crystallizes in triclinic space group P1 with a=1.195 1 (2) nm,b =1.252 0(2) nm,c=2.146 0(4) nm,α=85.893(3)°,β=76.229(3)°,γ=62.714(3)°,V=2.769 0(8) nm3,C30H50Cu2Mo8 N18O27,Mr=1989.48,Dc=2.386 g·cm-3,μ(Mo Kα)=2.598 mm-1,F(000)=1 932,GOF=1.001,Z=2,the final R1=0.062 0 andwR2=0.153 4 for I＞2σ(Ⅰ).In complex 1,each 1,4-bth ligand acted as a tridentate-linker to bridge three Cu2+ ions and dimeric copper clusters [Cu2(1,4-bth)3]4+ were formed.Each dimeric copper cluster is connected to four same clusters forming parallel two dimensional (2D) sheets [Cu2(1,4-bth)3]n4n+.Then the [β-Mo8O26]4-anions through bonded to the Cu2+ ions as the pillars to construct a three dimensional (3D) framework,with the pcu alpha-Po primitive cubic topology; the thermal analysis illustrate that compound 1 retains a comparatively good thermal stability.CCDC:865416.
