2-{4-[Acetyl(ethyl)amino]benzenesulfonamido}benzoic acid

In the title compound, C18H21NO4S, the aromatic rings are almost normal to each other, with a dihedral angle of 89.27 (18)°. The molecular conformation is stabilized by an intramolecular C—H⋯O interaction, which generates an S(6) motif. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds lead to the formation of chains propagating along [010]. Neighbouring chains are linked via a C—H⋯π interaction. The –CH2CH2CH3 atoms of the butyl group are disordered over two sets of sites, with a refined site-occupancy ratio of 0.536 (16):0.464 (16).

In the title compound, C17H19NO4S, the terminal ethyl group is disordered over two sets of sites, with refined site occupancies of 0.536 (7) and 0.464 (7). The dihedral angle between the two aromatic rings is 81.92 (12)°. The molecular conformation is stabilized by intramolecular N—H⋯O and C—H⋯O hydrogen bonds, which generate S(6) motifs. In the crystal, molecules are linked by C—H⋯O hydrogen bonds, forming chains along the b axis.

The title molecule, C16H14N2O4S, adopts an L-shaped conformation, with the central C—S—N—C torsion angle being −69.1 (3)°. The two benzene rings form a dihedral angle of 89.94 (15)°. The molecular conformation may be influenced by a weak intramolecular C—H⋯O hydrogen bond which generates an S(6) ring motif. In the crystal, molecules are linked by N—H⋯O and weak C—H⋯O hydrogen bonds, forming chains propagating along the b axis. Weak C—H⋯N hydrogen bonds connect the chains into a two-dimensional network parallel to (011). The crystal studied was an inversion twin, the ratio of components being 0.7 (1):0.3 (1).
