title: 3-Chloro-N-(4-sulfamoylphen-yl)propanamide.
abstract: In the title compound, C(9)H(11)ClN(2)O(3)S, the dihedral angle between the benzene ring and the amido -NHCO- plane is 15.0 (2)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, the amino NH(2) group is involved in inter-molecular N-H⋯O hydrogen bonds, which connect the mol-ecules 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 inter-action with a centroid-centroid distance of 3.7447 (12) Å is also observed.
