| Summary: | In the title compound, C15H21ClN2OS, the central chromophore moiety (C2N2OS) is approximately planar, with a maximum deviation of −0.027 (1) Å, and is oriented at a dihedral angle of 86.7 (1)° with respect to the chlorophenyl ring. An intramolecular N—H...O hydrogen bond stabilizes the molecular conformation. In the crystal, molecules associate via N—H...S hydrogen bonds, forming inversion dimers with motif R22(8). These dimers are further connected by N—H...O hydrogen bonds, forming R22(12) dimers. As a result, hydrogen-bonded chains running along [110] are formed. C—H...S interactions also occur. The terminal two C atoms of the butyl chain are disordered over two positions with an occupancy ratio of 0.54:0.46.
