title: Poly[piperazine-1,4-diium [μ(4)-chlorido-μ(3)-chlorido-tri-μ(2)-chlorido-chloridodicadmate(II)] monohydrate].
abstract: In the title compound, {(C(5)H(14)N(2))[Cd(2)Cl(6)]·H(2)O}(n), the asymmetric unit contains one piperazinediium cation, one [Cd(2)Cl(6)](2-) anion and a water mol-ecule. The coordination geometries of the two Cd(2+) cations are distorted octa-hedral. Adjacent Cd(II) atoms are inter-connected alternately by paired chloride bridges, generating polymeric chains parallel to [010]. Neighbouring chains are connected by O-H⋯Cl hydrogen bonds involving the water mol-ecules, forming layers at z = n/2. The crystal packing is further stabilized by inter-molecular N-H⋯Cl and N-H⋯O hydrogen bonds, one of which is bifurcated.
