title: 2,2'-(Disulfanedi-yl)dianilinium dichloride dihydrate.
abstract: In the title hydrated mol-ecular salt, C12H14N2S2 (2+)·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 inter-actions [centroid-centroid separation = 3.730 (3) Å] are also observed.
