基于柔性的双三氮唑基配体和刚性的芳香羧酸,合成得到了一个一维链状铜配位聚合物[Cu2(bza)4(btx)]n (1)(btx=1,4-二(1,2,4-三唑基-1-基甲基)苯,Hbza=苯甲酸),并通过元素分析、红外光谱、X-射线单晶衍射、热分析、荧光光谱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,P1-空间群.在化合物1中,羧酸根均采取双齿桥联的模式,4个苯甲酸配体螯合2个铜离子构成1个双核铜单元(Cu-Cu键的距离为0.26 nm),这些双核铜单元又通过柔性双三氮唑基配体桥联形成一维链状的结构；热分析表明该化合物具有相对较高的热稳定性,室温下的固态荧光测试发现,在398 nm激发下,化合物1发射出绿色光.

A one dimensional chainlike copper coordination polymer [Cu2(bza)4(btx)]n (1) (btx=1,4-bis(1,2,4-triazol-1-ylmethyl)benzene,Hbza=benzoic acid) based on binuclear copper units and the flexible bis(triazole) ligands has been synthesized and characterized by element analysis,IR spectra,single-crystal X-ray diffraction,thermalanalysis,luminescent property.The crystallographic data shows that complex 1 crystallizes in triclinic spacegroup P1- with a=1.063 70(10) nm,b=1.251 38(12) nm,c=1.530 15(14) nm,α=93.662(2)°,β=92.369(2)°,γ=104.387(2)°,V=1.965 4(3) nm3,C40H32Cu2N6O8,Mr=851.80,Dc=1.439 g·cm-3,μ(Mo Kα)=1.141 mm-1,F(000)=872,GOF=0.919,Z=2,the final R1=0.052 7 and wR2=0.095 7 for I＞2σ-(I).In 1,all the carboxylate ligands adopt the bidentate bridging mode binding two Cu atoms,and four bza- ligands connect the neighboring two copper ions in a chelating coordinated mode to form a binuclear copper cluster (d(Cu-Cu)=0.26 nm).Then the neighboring binuclear copper clusters are further linked by the flexible bis (triazole) ligands generating the infinite one dimensional chains.The thermal analysis illustrate that compound 1 retains a comparatively good thermal stability and the luminescent spectrum shows that complex 1 shows strong fluorescent emission with a maximum at 530 nm at λex=398 nm.CCDC:854824.
