A one dimensional chainlike copper coordination polymer [Cu-2(bza)(4)(btx)](n) (1) (btx=1,4-bis(1,2,4-triazol-1-ylmethyl)benzene, Elbza=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, thermal analysis, luminescent property. The crystallographic data shows that complex 1 crystallizes in triclinic space group P (1) over bar with a=1.063 70(10) nm, b=1.251 38(12) nm, c=1.530 15(14) nm, alpha=93.662(2)degrees, beta=92.369(2)degrees, gamma=104.387(2)degrees, V=1.965 4(3) nm(3), C40H32Cu2N6O8, M-r=851.80, D-o=1.439 g.cm(-3), mu(Mo K alpha)=1.141 mm(-1), F(000)=872, GOF=0.919, Z=2, the final R-1=0.052 7 and wR(2)=0.095 7 for I>2 sigma(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 lambda(ex)=398 nm.
