The title compound, (C7H10N)3[SbCl5]Cl·H2O, consists of 4-methyl­anilinium cations, Cl− and [SbCl5]2− anions and water mol­ecules. 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 [SbCl5]2− anions related by an inversion center are joined by Sb⋯Cl inter­actions [Sb⋯Cl = 3.7273 (14) Å] into an [Sb2Cl10]4− dimer with two bridging Cl atoms. The anions, water mol­ecules 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-methyl­anilinium cations are packed between these layers.
