2,2'-Diaminodiphenyl Disulfide Hemihydrate

The stereochemistry of 2,2′-diaminodiphenyl disulfide hemihydrate, C₁₂H₁₂N₂S₂.0.5H₂O, differs significantly from that of the corresponding anhydrous compound. The conformational difference is a consequence of the O—H...N and N—H...O intermolecular hydrogen bonding between the C₁₂H₁₂N₂S₂ and water molecules. The molecule is characterized by a skewed central moiety with a C—S—S—C torsion angle of 75.2 (1)°.
