摘要 用乙酸铜、二吡啶胺和丙二酸在水热条件下反应生成新的配合物1,结构式为[Cu(Hdpa)(H_2O)(mal)]·(H_2O)(Hdpa=2,2’-二吡啶胺,mal=丙二酸根阴离子).X-射线单晶衍射测定配合物1结晶在三斜晶系,Pī空间群,晶胞参数为:a=7.2354(6),b=9.6186(8),c=11.4308(11),α=82.773(2)°,β=71.555(2)°,γ=74.838(2)°.中心铜离子是五配位,其中3个Cu-O键长分别是1.936(2)和2.273(2),2个Cu-N键长分别是1.997(2)和1.992(3).配合物1分子通过氢键和π-π堆积作用形成三维超分子结构.配合物1有蓝紫色荧光. The reaction of Cu(Hdpa) ( H2O) (real) ·H2O and 2,2' -dipyridylamine(Hdpa) with malonic acid (mal) in a acidic hydro( solvo) -thermal solution afforded a new coordination complex, namely [ Cu(Hdpa) ( H2O) (mal)]·(H2O) ( 1 ). The X-ray diffraction analysis revealed that crystallizes in the centrosymmetric space group Pi with the following cell parameters : a=7.2354(6),b=9.6186(8),c=11.4308(11),α=82.773(2)°,β=71.555(2)°,γ=74.838(2)° In Complex 1 Cu2+ cation are five- coordinate in a tetragonal pyramidal structure with three different Cu-O bond lengths of 1. 936 (2), 2. 273 (2)A and two different Cu-N bond lengths of 1. 992 (3), 1. 997 (2). Complex t assembles into a 3D supramolecular structure by intermolecular hydrogen bonding and Pi-Pi stacking. Complex 1 is a blue-purple fluorescent compound.
