一维链状Ag(Ⅰ)席夫碱配合物的合成和结构表征

Synthesis and crystal structure of Schiff base Ag(Ⅰ)complex with one-dimensional chain structure

以2-醛基吡啶和1,2-二(对氨基苯氧基)乙烷进行缩合得到Schiff碱配体L,然后与AgSbF6进行配位反应,得到了席夫碱配合物[Ag(L)SbF6]n,用元素分析、FT-IR和X-射线单晶衍射进行了表征.结果表明,配合物属于单斜晶系,P21/n空间群,每个Ag(Ⅰ)的配位环境均为扭曲四面体,每个配体L通过其两端的2个N原子同2个金属离子配位桥联形成一维螺旋链结构.

The Schiff base ligand L was synthesized from condensation reaction of 1,2-（p-aminophe- noxy） ethane with 2-Pyridinecarboxaldehyde. AgSbF6 react with L to give the Schiff base complex lag （L） SbF6 In, and characterized by elemental analysis, FT-IR and single crystal X-ray diffraction. The re- sults of structural analysis indicate that the complex is monoclinic crystallize and space group P21/n, the coordination environment 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） helical chain structure.
