The asymmetric unit of the title compound, (C6H7ClN)4[SnCl6]Cl2, comprises two 4-chloroanilinium cations, half of an [SnCl6]2− anion and a Cl− anion. The SnIV atom, located on a special position on a twofold rotation axis, exhibits an octahedral environment. In the crystal, molecules are linked by N—H⋯Cl hydrogen bonds between the 4-chloroanilinium cations, [SnCl6]2− anions and Cl− anions.
