摘要:2,2'-二吡啶胺配体由于其具有多个配位原子且能有效地螯合金属离子,在配合物的合
成中被广泛的应用。本文在 2,2'-二吡啶胺分子上引入吡唑单元,一方面可以增加配位原子的
数目,另一方面可以增加螯合金属离子的位点,有利于构建多核的配合物。因此本文从含吡
唑的 2,2'-二吡啶胺配体出发,采用溶剂热法合成了一个结构新颖的双核铜(I) 配合物,对它
进行了元素分析、红外光谱等表征,并用 X-射线单晶衍射测定了其晶体结构。单晶测试结
果显示,配合物是一个双核的结构,每个铜原子均采用五配位的三角双锥配位构型,双核单
元通过分子间相互作用形成一维链状结构。

Abstract: 2,2'-dipyridylamine (2,2-dpa) is a flexible bidentate chelating ligand and can chelate
effectively metal ions. In the past decades, many plexes of 2,2-dpa have been
prepared with interesting supramolecular structures. In this paper, one pyrazole molecule has been
connected to 2,2-dpa, afforing a novel ligand, which has more coordiantion atoms. Here, staring
from the novel ligand, one binuclear copper(I) complex has been synthesized under solvothermal
conditions and characterized by elemental analyses, IR and X-ray single-crystal diffraction
measurements. plex, each copper center exhibits a distorted trigonal-bipyramidal geometry
and the binuclear units are linked by intermolecular π…πinteraction
