2,2′-(Disulfanedi­yl)dianilinium dichloride dihydrate

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 π–π stacking inter­actions [centroid–centroid separation = 3.730 (3) Å] are also observed.
