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