The asymmetric unit of the title compound, (C(4)H(12)N(2))(3)InCl(6)·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.
标题化合物（C₄H₁₂N₂）₃[InCl₆]₂·4H₂O的不对称单元由一个半独立的哌嗪鎓阳离子、一个六氯铟酸盐阴离子和两个水分子组成。In(III)离子为六配位，形成近似规则的八面体排列。在晶体中，阳离子和阴离子的交替层平行于(10[化学式：见正文])排列，并通过分子内和分子间的N-H⋯O、O-H⋯Cl、C-H⋯O和N-H⋯Cl氢键与水分子相连，形成复杂的三维网络。层内通过弱的分子间C-H⋯Cl相互作用提供额外的稳定性。
