以咪唑对苯甲酸和溴化锌为原料,以乙醇-水为溶剂,通过溶剂热反应合成了一种新型配位聚合物[Zn(C10H7N2O2)Br]n,并对其进行了元素分析、红外光谱表征和X射线单晶衍射测定。该配位聚合物属单斜晶系,空间群P2(1)/c,a=0.83624(6)nm,b=1.5878(1)nm,c=0.8720(6)nm,β=107.804(1)°,V=1.1024(1)nm3,Z=4,dc=2.003g/cm3,μ=5.836mm2,F(000)=648。该晶体通过配位键的连接形成二维网状结构。荧光光谱结果表明,配合物在蓝光区有较强的发射。

A novel coordination polymer[ Zn（C10H7N2O2） Br] n was synthesized by solvothermal reaction of ZnBr2 · 2H2O and 4-（ imidazole-l-yl）-benzoic acid. The structure was characterized by elemental analysis and IR spectroscopy as well as X-ray single crystal diffractometer. The result shows the crystal in monoclinic crystal system and P2（ 1 ）/c space group. Crystallographic date： a =0. 83624（6） nm, b = 1.5878 （1） nm, c =0.8720 （6） nm, β =107. 804 （1）°,V =1.1024（1） nm, Z =4, dc =2.003 g/ cm^3,μ =5. 836 mm^2 ,F（000） =648. X-ray analysis reveals that an infinite 2D network was formed by coordination bonds. The photoluminescence property of the complex in the solid state was studied at room temperature and strong blue emission was observed.
