In the title compound, C13H9ClN2O5S, the dihedral angle between the benzene rings is 74.86 (11)°. The molecule is twisted at the S atom, with a dihedral angle of 82.53 (13)° between the sulfonyl benzene ring and the S—N—C=O segment. In the crystal, molecules are linked into inversion dimers through pairs of N—HO hydrogen bonds, thereby forming R22(8) loops. Molecules are linked into C(7) [010] chains by weak C—HO hydrogen bonds, and C—Hπ interactions are also observed.

In the title compound, C15H15NO4S, the dihedral angle between the benzene rings is 88.87 (1)°. In the crystal, adjacent molecules form inversion dimers through pairs of strong N—HO hydrogen bonds, generating R22(8) loops. Two C—Hπ interactions and an aromatic π–π interaction [centroid–centroid separation = 3.8191 (1) Å] are also observed.
