双核Ag(Ⅰ)配合物的合成及晶体结构

用1,2-二(邻氨基苯氧基)乙烷分别与AgClO4和AgBF4进行配位反应,得到了两个配合物1,2,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,C2/c空间群,配合物2属于单斜晶系,P21/c空间群。配合物1和2的每个Ag(Ⅰ)离子的配位环境均为扭曲的平面三角型,每个Ag(Ⅰ)离子与同一配体两端的氮原子配位,形成11元环状结构;然后,配体苯环上的碳原子与Ag(Ⅰ)离子配位,从而形成穴状双核配合物。

Synthesis and Crystal Structure of Dinuclear Ag ( Ⅰ ) Complex

The two complexes(1 and 2) were synthesized by the reactions between 1,2-(o-aminophenoxy)ethane and AgClO4 or AgBF4,and characterized by elemental analysis,FTIR and X-ray single crystal diffraction.The results of structural analysis indicated that the complex 1 was monoclinic crystallize and space group C2/c and the complex 2 was monoclinic crystallize and space group P21/c,and the coordination environment of each Ag ion in complex 1 and 2 were all planar triangular,while each Ag ion and the nitrogen atoms of the both ends in the same ligand coordinated to form a 11 ring structure,then the carbon atoms of the benzene ring in ligand and Ag ions coordinated to form the cave-shaped dinuclear complex.
