1-(2,5-Dimethyl-phen-yl)piperazine-1,4-diium tetra-chloridozincate monohydrate.

In the title compound, (C(12)H(20)N(2))[ZnCl(4)]·H(2)O, the two piperazine N atoms are protonated and the ZnCl(4) anions adopt a slightly distorted tetra-hedral configuration. In the crystal, O-H⋯Cl hydrogen bonds link the tetra-chloridozincate anions and the water mol-ecules into corrugated inorganic chains parallel to [010]. The crystal structure is stabilized by N-H⋯Cl, N-H⋯O and O-H⋯Cl hydrogen bonds, with the N-H hydrogen bond originating from one of the two N atoms being trifurcated.
