摘　　要：以2-苯基-4-喹啉羧酸和2,4-二氨基-6-苯基-三嗪作为配体,合成了双核锌配合物[Zn(C16H11NO2)2(C9H9N5)]2;利用红外光谱仪和X射线单晶衍射仪分析了产物的结构,测定了其荧光性能.结果表明,合成产物属于三斜晶系,P-1空间群,晶胞参数为:a=1.090 34(7)nm,b=1.286 55(9)nm,c=1.306 14(9)nm,α=86.009 0(10)°,β=72.141 0(10)°,γ=86.177 0(10)°,Z=1,Dc=1.432g/cm3,μ=0.762mm-1,F(000)=772,R1=0.027 5,wR2=0.071 7.双核锌配合物中的两个锌原子之间通过四个羧基形成轮桨状的二核单元Zn2(CO2)4;该二核单元之间通过氢键相互作用形成三维结构.此外,化合物在286nm的激发波长下于411nm处产生荧光发射峰.Abstract： Binuclear Zn（II） complex[Zn（C16H11NO2）2（C9H9N5）]212 was obtained with 2-phenyl- quinoline-4-carboxylic acid and 2,4-diamino-6-phenyl-triazine as the mixed ligands. The structure of as-synthesized product was characterized by means of infrared spectrometry and single-crystal X-ray diffraction, and its fluorescence properties were examined as well. Results indicate that as synthesized complex crystallizes in triclinic system of space group P-1, with crystal cell parameters of a = 1. 090 34（7）,b = 1. 286 55 （9）,c = 1. 306 14 （9） nm, a = 86.009 0（10）°,β= 72.141 0 （10°,γ = 86.177 0（10）°,Z = 1,Dc= 1.432 g/cm3,μ = 0.762 mm -1,F（000）=772,R1=0.027 5, and wR2= 0.0717. Besides, the two zinc atoms in as-synthesized compound are bridged into paddle-wheel shaped Znz （CO2）4 binuclear unit by four carboxyl groups, and the binuclear unit is further linked into three-dimensional structure by hy- drogen-bond interactions. In addition, the as-synthesized compound shows an emission spectrum at 411 nm upon excitation at 286 nm.
