The crystal structure of the title compound, [Cd(2)Cl(2)(C(2)H(8)N(2))(4)]Cl(2), consists of binuclear centrosymmetric Cd(2)(C(2)H(8)N(2))(4)Cl(2) cations and discrete chloride anions. The Cd(II) cation is coordinated by four N atoms of two ethyl-enediamine ligands and two symmetry-related chloride anions within a distorted CdN(4)Cl(2) octa-hedron. Two Cd(II) cations are connected by two chloride anions via μ(2)-coordination, forming a four-membered Cd(2)Cl(2) ring. The uncoordinated chloride anions are linked to the amino groups via N-H⋯Cl hydrogen bonding. Two C atoms of one of the two crystallographically independent ethyl-enediamine ligands are disordered and were refined using a split model [occupancy ratio 0.674 (9):0.326 (9)].
标题化合物[Cd₂Cl₂(C₂H₈N₂)₄]Cl₂的晶体结构由双核中心对称的[Cd₂(C₂H₈N₂)₄Cl₂]²⁺阳离子和离散的氯离子阴离子组成。Cd(II)阳离子在一个扭曲的CdN₄Cl₂八面体中由两个乙二胺配体的四个N原子和两个对称相关的氯离子阴离子配位。两个Cd(II)阳离子通过两个氯离子阴离子经由μ₂配位相连，形成一个四元Cd₂Cl₂环。未配位的氯离子阴离子通过N—H⋯Cl氢键与氨基相连。两个晶体学独立的乙二胺配体之一的两个C原子无序，并使用分裂模型[占有率 0.674 (9):0.326 (9)]进行精修。
