Abstract: The asymmetric unit of the title compound, C₂₁H₁₈ClN₃O₂S, contains two molecules in which the bond lengths and angles are almost identical. Intramolecular N-HS hydrogen bonds result in the formation of two five-membered rings. In the crystal structure, intermolecular N-HO hydrogen bonds link the molecules into centrosymmetric dimers; these dimers are linked via intermolecular O-HS hydrogen bonds, leading to infinite corrugated layers parallel to the bc plane through R₂²(16) ring motifs.
