摘　　要：合成含氟席夫碱,双-(5-氟水杨醛)缩邻苯二胺双席夫碱(C20H14F2N2O2),化合物单晶进行了X射线晶体衍射和分子结构分析。结果表明,化合物属单斜晶系,P2(1)/c空间群,晶胞参数a=0.609 38(8),b=1.634 7(2),c=9.447 4(2),V=165.19(4)nm3,Z=4,Dc=1.417,μ(MoKα)=0.11 mm,F(000)=728,T=293 K,R=0.032。制备了其锌配合物C20H12F2N2O2Zn。通过核磁共振谱、红外光谱、元素分析等测试技术对此化合物进行了结构表征和分析,探讨了其固态和溶液的荧光性能。Bis-Schiff-base-5-fluorosalicylaldehyde-o-phenylenediamine was prepared. The crystal and molecular structure was investigated by X-ray analysis. The crystal is in the monoelinic space group P2 （ 1 ）/c with a ---0.609 38（8）, b =1.634 7（2）, e=9.447 4（2）, V=165.19（4） nm^3, Z=4, Dc =1.417,μ（MoKα） ： 0. 11 mm, F（000） =728, T=293 K, R =0.032. The Zn（ 11 ） complex（C20H12F2N2O2Zn） was prepared and characterized by the analytical and spectroscopic methods and its fluorescence properties were also studied in the solution and in the solid state.
