摘　　要：本文以2-醛基吡啶和1,4-二(对氨基苯氧基)丁烷进行缩合得到Schiff碱配体L(1,4-双-(N-(2-吡啶甲亚胺基)苯氧基)丁烷),再同AgSbF6,进行配位反应,得到了席夫碱配合物[Ag(L)SbF6]n.2CHCl3(1),并用元素分析,FT-IR和X-射线单晶衍射进行了表征。结果表明,配合物1属于单斜晶系,P21/c空间群,晶胞参数为:a=1.19100(16)nm,b=1.8073(2)nm,c=1.8058(2)nm,β=98.625(4)°,V=3.8431(9)nm3,Z=4,R1=0.0589,wR2=0.1112。每个Ag(I)的几何构型是扭曲四面体,每个配体L通过其两端的两个氮原子同两个金属离子配位桥联形成一维链结构。The Schiff base ligand L was synthesized by the reaction of 1,4-（p-aminophenoxy）butane with 2-Pyridinecarboxaldehyde,AgSbF6 react with L to give Schiff base complex[Ag（L）SbF6]n·2CHCl3（1）.The complex was characterized by elemental analysis,FT-IR and single crystal X-ray diffraction.The results of structural analysis indicate that the complex crystallizes in the monoclinic crystallize and space group P21/c,with the crystal cell parameters：a=1.19100（16）nm,b=1.8073（2）nm,c=1.8058（2）nm,β=98.625（4）°,V=3.8431（9）nm3,Z=4,R1 =0.0589,wR2 =0.1112.The coordination geometry of Ag（I）is a distorted tetrahedron,each L ligand links two metal atoms using both ends two nitrogen atom to generate a one-dimensional（1D）chain structure.
