摘要
本文以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,再分别同AgNO3和AgClO4进行配位反应,得到了2个配合物[Ag2(NO3)2L](1)和{[AgL]ClO4}n(2),并用元素分析,FTIR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,Ag(I)的配位环境为平面三角形,配体L同时和2个Ag(Ⅰ)离子配位形成双核配合物。配合物2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个氮原子同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-aminophenoxy）ethane with 2-Pyridinecarboxaldehyde.AgNO3 and AgClO4 each react with L to give two complexes [Ag2（NO3）2L]（1） and {ClO4}n（2）,and characterized by elemental analysis,FTIR and single crystal X-ray diffraction.The results of structural analysis indicate that the complex 1 is monoclinic crystallize and space group P21/c,the coordination environment of Ag（Ⅰ） is a plane triangular,each L ligand links two metal atoms form a binuclear complex.The complex 2 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.
