Abstract: 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.
