In the title compound, C25H20N2O5S, the phenyl ring makes dihedral angles of 89.88 (8) and 13.98 (8)°, respectively, with the indole ring system and the nitrobenzene ring. The dihedral angle between the indole ring system and the nitrobenzene ring is 88.48 (11)°. The molecular structure is stabilized by a weak intramolecular C—H
O interaction. In the crystal, π–π interactions, with centroid–centroid distances of 3.6741 (18) and 3.8873 (17) Å, link the molecules into layers parallel to the ab plane.

In the title compound C24H17BrN2O5S, the phenyl ring makes dihedral angles of 85.4 (2) and 8.8 (2)° with the indole ring system and the nitrobenzene ring, respectively, while the indole ring system and nitrobenzene ring make a dihedral angle of 80.1 (2)°. In the crystal, weak C—HO interactions link the molecules, forming a two-dimensional network parallel to the bc plane.

The title salt crystallized with two anions and two cations in the asymmetric unit, together with three water molecules. In the crystal, the anions are linked via O—HO hydrogen bonds, involving the water molecules, forming chains along [100] and the cations are linked to these chains by N—HO hydrogen bonds.
