In the title OIL 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—H.
Cl hydrogen bonds involving the water molecules, forming layers at z = n/2.The crystal packing is further stabilized by intermolecular Dispenser Napkins N—H.Cl and N—H.O hydrogen bonds, one of which is bifurcated.
