| 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。 |

| Abstract: 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 {[AgL]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.
