Tris(piperazine-1,4-diium) bis­[hexa­chloridoindate(III)] tetra­hydrate

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 hexa­chloridoindate anion and two mol­ecules of water. The In(III) ion is six-coordinated and forms a quasi-regular octa­hedral arrangement. In the crystal, alternating layers of cations and anions are arranged parallel to (10[Image: see text]) and are linked with the water mol­ecules via intra- and inter­molecular 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 inter­molecular C—H⋯Cl inter­actions.
