Abstract: The title compound, C₁₈H₁₉N₃O₃S, was identified as one of two possible isomers. Key bond lengths are N-N 1.402  (2)  Å and N-S 1.6894  (18)  Å. Classical hydrogen bonds N-HO connect the molecules to form inversion-symmetric dimers, which are further linked by a weak C-HO hydrogen bond, forming ribbons.
