In the title compound, C6H10N2OS, the 2-sulfanylideneimidazolidin-4-one fragment is essentially planar (r.m.s. deviation = 0.0033 Å). In the crystal, one amino group is involved in N—HO hydrogen bonding, which links pairs of molecules into inversion dimers, while the other amino group generates weak N—HS hydrogen bonds, which link these dimers into chains in [10-1]. The chains are further aggregated into layers parallel to the ac plane through weak C—HO interactions.

The title compound, C15H14N2OS2, adopts a helix conformation. An intramolecular N—HO hydrogen bond leads to a six-membered pseudo-ring [r.m.s. deviation = 0.0212 Å, maximum deviation = 0.033 (1) Å for the N atom bearing the benzoyl group] in the central unit. The benzene and (methylsulfanyl)benzene ring [r.m.s = 0.0028 Å and largest deviation of 0.067 (3) Å for the methylsulfanyl C atom] make dihedral angles of 31.76 (8) and 54.68 (6)°, respectively, with the pseudo-ring plane. The dihedral angle between the benzene rings is 85.71 (8)°. In the crystal, pairs of weak N—HS interactions form inversion dimers and mediate a linear chain along [001].
