title: Tris(4-methyl-anilinium) penta-chlorido-anti-monate(III) chloride monohydrate.
abstract: The title compound, (C(7)H(10)N)(3)[SbCl(5)]Cl·H(2)O, consists of 4-methyl-anilinium cations, Cl(-) and [SbCl(5)](2-) anions and water mol-ecules. The five Cl atoms bound to Sb [Sb-Cl = 2.4043 (9)-2.6262 (11) Å] form a square-pyramidal coordination environment. In addition, two [SbCl(5)](2-) anions related by an inversion center are joined by Sb⋯Cl inter-actions [Sb⋯Cl = 3.7273 (14) Å] into an [Sb(2)Cl(10)](4-) dimer with two bridging Cl atoms. The anions, water mol-ecules and ammonium groups of the cations are linked by N-H⋯Cl, N-H⋯O and O-H⋯Cl hydrogen bonds, forming layers parallel to the ac plane. The benzene rings of the 4-methyl-anilinium cations are packed between these layers.
