S, a halogenated sulfonamide, was prepared by basic hydrolysis of the methyl ester. In the crystal, molecules form centrosymmetric hydrogen-bonded dimers
via
the carboxyl groups. These dimers are further linked by N—H⋯O interactions involving the carbonyl O and amide H atoms, forming a ribbon-like structure propagating in [010]. These ribbons are further linked
via
C—H⋯O interactions, forming a three-dimensional network.
