In the title compound, C24H18N2O5S, the S atom has a distorted tetrahedral configuration, with bond angles varying from 105.11 (7) to 119.98 (8)°. As a result of the electron-withdrawing character of the phenylsulfonyl group, the N—Csp2 bond lengths [1.414 (2) and 1.413 (2) Å] are slightly longer than the reported value of 1.355 (14) Å for N atoms with a planar configuration. The indole moiety is essentially planar, with a maximum deviation of 0.0177 (14) Å for the N atom. The phenyl ring of the sulfonyl substituent makes a dihedral angle of 85.70 (7)° with the mean plane of the indole moiety. The molecular structure features intramolecular C—H
O hydrogen bonds, which generate S(6) and S(12) ring motifs. In the crystal, adjacent molecules are linked via C—HO hydrogen bonds, forming infinite C(7) chains running along the a-axis direction. The crystal packing also features C—Hπ interactions, which form a three-dimensional structure.

In the title compound, C25H19FN2O5S, the substituted phenyl ring makes a dihedral angle of 12.26 (9)° with the indole ring system. The nitro group is twisted at an angle of 26.92 (8)° out of the plane of the ring to which it is attached. The molecular structure is stabilized by weak C—HO hydrogen bonds. In the crystal, weak C—HO, C—HF and π–π [centroid–centroid distance = 3.6645 (11) Å] interactions link the molecules, forming a three-dimensional network.

In the title compound, C18H16ClNO2S, the indole ring system forms a dihedral angle of 75.07 (8)° with the phenyl ring. The molecular structure is stabilized by a weak intramolecular C—HO hydrogen bond. In the crystal, molecules are linked by weak C—HO hydrogen bonds, forming a chain along [10-1]. C—Hπ interactions are also observed, leading to a three-dimensional network.

In the title compound, C25H19ClN2O5S, the phenyl ring forms dihedral angles of 79.62 (12) and 80.02 (13)° with the indole ring system and the benzene ring, respectively. The nitro group is twisted at an angle of 22.39 (11)° with respect to the attached benzene ring. In the crystal, molecules assemble into double layers in the ab plane via C—HO interactions.

In the title compound, C18H16BrNO3S, the dihedral angle between the phenyl ring and the indole ring system is 89.91 (11)°. The molecular structure features weak C—HO and C—HBr hydrogen bonds. In the crystal, molecules are linked by weak C—HO hydrogen bonds, forming chains along the a-axis direction. The chains are further linked by C—Hπ interactions, forming a layer parallel to the ab plane.
