The structure of the title compound, catena-poly[[cadmium(II)-di-mu-chlorido-mu-(1,4-diazoniabicyclo[2.2.2]octane-1-carboxylato)] [[aquachloridocadmium(II)]-di-mu-chlorido] dihydrate], {[Cd(C8H15N2O2)Cl-2][CdCl3(H2O)]center dot 2H(2)O}(n), contains two kinds of independent one-dimensional chain, viz. {[Cd(C8H15N2O2)Cl-2](+)}(n) and {[CdCl3(H2O)](-)}(n), and uncoordinated water molecules. Each Cd-II cation in the {[Cd(C8H15N2O2)Cl-2](+)}(n) chain is octahedrally coordinated by two pairs of bridging chloride ligands and two O atoms from different bridging carboxylate groups. Cd-II 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.
