2,2′-(Disulfanediyl)dianilinium dichloride dihydrate

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