The structure of the title compound, catena-poly[[cadmium(II)-di-μ-chlorido-μ-(1,4-diazoniabicyclo[2.2.2]octane-1-carboxylato)] [[aquachloridocadmium(II)]-di-μ-chlorido] dihydrate], {[Cd(C₈H₁₅N₂O₂)Cl₂][CdCl₃(H₂O)]·2H₂O}n, contains two kinds of independent one-dimensional chain, viz. {[Cd(C₈H₁₅N₂O₂)Cl₂]⁺}n and {[CdCl₃(H₂O)]⁻}n, and uncoordinated water molecules. Each CdII cation in the {[Cd(C₈H₁₅N₂O₂)Cl₂]⁺}n chain is octahedrally coordinated by two pairs of bridging chloride ligands and two O atoms from different bridging carboxylate groups. CdII cations in the {[CdCl₃(H₂O)]⁻}n chain are also octahedrally surrounded by four bridging chloride ligands, one terminal chloride ligand and one coordinated water molecule. Hydrogen bonds between solvent water molecules and these two independent chains generate a three-dimensional framework containing two-dimensional zigzag layers.
标题化合物链状聚[[镉（II）-二-μ-氯-μ-（1,4-二氮杂双环[2.2.2]辛烷-1-羧酸根）][[水合氯镉（II）]-二-μ-氯]二水合物]，{[Cd(C₈H₁₅N₂O₂)Cl₂][CdCl₃(H₂O)]·2H₂O}n，其结构包含两种独立的一维链，即{[Cd(C₈H₁₅N₂O₂)Cl₂]⁺}n和{[CdCl₃(H₂O)]⁻}n，以及未配位的水分子。{[Cd(C₈H₁₅N₂O₂)Cl₂]⁺}n链中的每个CdII阳离子由两对桥连氯配体和来自不同桥连羧酸根基团的两个O原子八面体配位。{[CdCl₃(H₂O)]⁻}n链中的CdII阳离子也被四个桥连氯配体、一个端基氯配体和一个配位水分子八面体包围。溶剂水分子与这两条独立链之间的氢键形成了一个包含二维锯齿层的三维框架。
