Tris(piperazine-1,4-diium) bis-[hexa-chloridoindate(III)] tetra-hydrate.

The asymmetric unit of the title compound, (C(4)H(12)N(2))(3)[InCl(6)](2)·4H(2)O, consists of one and half independent piperazinium cations, an hexa-chloridoindate anion and two mol-ecules of water. The In(III) ion is six-coordinated and forms a quasi-regular octa-hedral arrangement. In the crystal, alternating layers of cations and anions are arranged parallel to (10[Formula: see text]) and are linked with the water mol-ecules via intra- and inter-molecular N-H⋯O, O-H⋯Cl, C-H⋯O and N-H⋯Cl hydrogen bonds, forming a complex three-dimensional network. Additional stabilization within the layers is provided by weak inter-molecular C-H⋯Cl inter-actions.
