摘　　要：以3-氨基-1,2,4-三氮唑为主配体、烟酸为结构调整剂,采用溶剂热法,控制三唑与酸的物质的量比为1∶1,合成了锌的金属配位聚合物{[（C2H3N4）7（H2O）2（μ-O）Zn6]·3NO3·3H2O}n。采用单晶衍射、XRD、热重分析、红外光谱、荧光分析等对其进行表征。结果表明,该配合物属于六方晶系,R-3空间群,晶胞参数为a=20.980（15）、b=20.980（15）、c=25.693（16）、γ=120°,最终偏离因子R1=0.063 6,wR2=0.159 3。生成的配位聚合物具有较强的荧光强度。In this work,3-amino-1,2,4-triazole as the main ligand,nicotinic acid as the chemical agents for structural adjustment.The proportion of triazole and acid was controlled for 1 ∶ 1. Zn（Ⅱ） coordination polymer { [（C2H3N4）7（H2O）2（μ-O） Zn6]·3NO3·3H2O}nhas been synthesized by solvothermal method. It was confirmed by X-ray-single-crystal diffraction,XRD,thermogravimetric analysis,infrared spectrum and fluorescent analysis. It belongs to the hexagonal crystal,R-3/n space group with a =20. 980（15）,b = 20. 980（15） ,c = 25. 693（16）,γ = 120°; R1= 0. 063 6,wR2= 0. 159 3. The compound have high fluorescence intensity.
