The majority of the title molecule, C28H34ClN3O9S, is disordered over two closely spaced sets of sites; the site occupancy of the major component = 0.542 (3). The conformation of each component is approximately U-shaped with the chlorobenzene ring forming the base and the indolinyl and sulfamoyl groups the sides; an intramolecular C—H...Cl hydrogen bond possibly contributes to the stabilization of the conformation. In the crystal, a corrugated layer structure parallel to the ab plane is formed by C—H...O and C—H...Cl hydrogen bonds together with C—H...π(ring) interactions.
