Abstract
The title compound, C10H14N4O2S, exists in the amine tautomeric form. The dihedral angle between the benzene and thiadiazolidine rings is 66.54 (19)°. In the crystal, molecules are linked by N—H...O and N—H...N hydrogen bonds into a layer parallel to the ac plane. The layers are further linked by C—H...O hydrogen bonds.
