新型含丙腈基和咪唑基三脚架配体-银(Ⅰ)配合物的合成与结构

摘要

设计合成了同时含有丙腈基和咪唑基的新型三脚架配体N,N-二(3-丙腈基)-[3-(1-咪唑基)]正丙胺(L),并与银盐按摩尔比1∶1和2∶1的比例反应,分别得到了配合物{[AgL]X｝n(X =BF-4,1a;X=ClO-4,1b)和{[Ag(L)2]ClO4}n(2),并用X射线单晶结构解析和电喷雾质谱等方法对其进行了表征.分析结果表明,配合物1a和1b为一维链状结构,而配合物2为单核结构.表明金属盐和配体的比例对配合物结构有很大影响.%New complexes { [ AgL]X}n(X = BF4- , la; X = C1O4- ,1b) and { [ Ag(L)2] C1O4} n(2) were synthesized by the reactions of corresponding silver( I ) salt with new tripodal ligand 3,3'-[3-( lH-imidazol-l-yl)propylazanediyl]dipropanenitrile(L) under ligand to metal ratio of 1: 1 and 2:1, respectively, and their structures were determined by single crystal X-ray diffraction and electrospray mass spectrometry. Complexes la and lb have one-dimensional(1D) chain structure while complex 2 is mononuclear. The results show that the metal to ligand ratio has subtle influence on the structure of the complexes.
