Abstract

The centrosymmetric dinuclear cadmium title complex, Cd(2)(C(6)H(18)N(4))(3)(4), was obtained by the reaction of N,N'-bis-(2-amino-eth-yl)ethane-1,2-diamine (trien) with Cd(NO(3))(2)·4H(2)O and sodium perchlorate in methanol. The Cd(II) cation is coordinated by four N atoms of a non-bridging trien ligand and by two N atoms of a bridging trien ligand in a slightly distorted octa-hedral coordination geometry. The bridging ligand shares another two N atoms with a neighboring symmetry-equivalent Cd(II) cation. The structure displays C-H⋯O and N-H⋯O hydrogen bonding. The perchlorate anion is disordered over two sets of sites in a 0.854 (7): 0.146 (7) ratio.

摘要

通过N,N'-双-(2-氨基乙基)乙二胺（三乙撑四胺，trien）与硝酸镉四水合物（Cd(NO₃)₂·4H₂O）以及高氯酸钠在甲醇中反应，得到了中心对称的双核镉标题配合物Cd₂(C₆H₁₈N₄)₃₄。镉(II)阳离子由一个非桥连三乙撑四胺配体的四个N原子和一个桥连三乙撑四胺配体的两个N原子配位，形成略微扭曲的八面体配位几何构型。桥连配体与相邻对称等效的镉(II)阳离子共享另外两个N原子。该结构呈现出C-H⋯O和N-H⋯O氢键。高氯酸根阴离子在两组位置上无序分布，比例为0.854 (7): 0.146 (7)。
