| Summary: | In the title compound, C9H11ClN2O3S, the dihedral angle between the benzene ring and the amido –NHCO– plane is 15.0 (2)°. An intramolecular C—H...O hydrogen bond generates an S(6) ring motif. In the crystal structure, the amino NH2 group is involved in intermolecular N—H...O hydrogen bonds, which connect the molecules into a double layer structure expanding parallel to the bc plane. The layers are further linked by an amido N—H...O hydrogen bond. Between the layers, a weak π–π interaction with a centroid–centroid distance of 3.7447 (12) Å is also observed.
