In the title hydrated molecular salt, C12H14N2S22+·2Cl−·2H2O, the dihedral angle between the benzene rings in the dication is 9.03 (17)° and the C—S—S—C torsion angle is 96.8 (2)°. The crystal packing can be described as alternating organic and anionic water layers lying parallel to (100), which are linked by N—HCl and N—HO hydrogen bonds. O—HCl hydrogen bonds and aromatic π–π stacking interactions [centroid–centroid separation = 3.730 (3) Å] are also observed.
