Abstract: 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-H...Cl and N-H...O hydrogen bonds. O-H...Cl hydrogen bonds and aromatic [pi]-[pi] stacking interactions [centroid-centroid separation = 3.730 (3) Å] are also observed.
