1,4-Diazo­niabi­cyclo­[2.2.2]octane tetra­chlorido­cadmate(II) monohydrate

The asymmetric unit of the title compound (C₆H₁₄N₂)[CdCl₄]·H₂O contained one 1,4-di­aza­bicyclo­[2.2.2]octane dication, a tetrahedral CdCl₄²⁻ anion and a lattice water mol­ecule. In the crystal, the solvate water mol­ecule inter­acts with the cationic and anionic species via N—H...O and O—H...Cl [O...Cl = 3.289 (7) Å] hydrogen-bond inter­actions, respectively, leading to a layered supramolecular structure extending parallel to (011).
