采用水热法合成了一种新的三维配位聚合物[Zn6(bta)4(2,2′-bipy)3](H3bta=1,3,5-苯三乙酸;2,2′-bipy=2,2′-二联吡啶),并通过X射线单晶结构分析、红外光谱、元素分析和热重分析对该配合物进行了表征.结构分析数据表明,该配合物属单斜晶系,Cc空间群,晶胞参数a=1.7714(4)nm,b=2.4391(5)nm,c=1.7120(3)nm,β=104·39(3)°,Z=4,V=7·165(2)nm^3,Dc=1·722g/cm^3,μ=2·065mm^-1,F(000)=3768,R1=0·0645,wR2=0·1424.荧光光谱结果表明,配合物具有良好的荧光性质.
A novel coordination polymer [ Zn6 (bta) 4 (2,2'-bipy) 3 ], with three-dimensional structure, was obtained via assembly of flexible tripodal ligand 1,3,5-benzenetriacetic acid( H3bta) with 2, 2'-bipy, Zn( NO3 )3· 6H2O under the hydrothermal condition. The X-ray single crystal diffraction analysis reveals that the complex is monoclinic with space group Cc, a = 1. 7714(4) nm, b =2. 4391 (5) nm, c = 1. 7120(3) nm, fl = 104. 39(3)°, Z =4, V =7. 165(2) nm^3, Dc = 1. 722 g/cm^3,μ = 2. 065 mm^-1, F(000) = 3768, R1 = 0. 0645, wR2 = 0. 1424 for 8019 observed reflections with goodness-of-fit 1. 050. The photoluminescence property of the complex in the solid state was studied at room temperature and strong blue emission was observed.
