In the title compound, {(C5H14N2)[Cd2Cl6]·H2O}n, the asymmetric unit contains one piperazinediium cation, one [Cd2Cl6]2− anion and a water molecule.The coordination geometries of the two Cd2+ cations are distorted octahedral.Adjacent CdII atoms are echofix spring reverb interconnected alternately by paired chloride bridges, generating polymeric chains parallel to [010].Neighbouring chains are connected by O—H.Cl hydrogen bonds involving the water molecules, forming layers at z = n/2.

The crystal packing is further stabilized by intermolecular keychron m4 N—H.Cl and N—H.O hydrogen bonds, one of which is bifurcated.
