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 interconnected alternately by paired chloride bridges, generating polymeric chains parallel to [010]. Neighbouring chains are connected by O—HCl hydrogen bonds involving the water molecules, forming layers at z = n/2. The crystal packing is further stabilized by intermolecular N—HCl and N—HO hydrogen bonds, one of which is bifurcated.
