In the title compound, C22H15N3O, the dihedral angle between the two indole units is 33.72 (3)°. The mol­ecular structure features a weak intra­molecular C—H...N inter­action. In the crystal, weak C—H...O and C—H...π inter­actions, forming a two-dimensional network parallel to the bc plane.

In the title compound C20H13N5, the dihedral angle between the carbazole ring system (r.m.s. deviation = 0.027 Å) and the pendant benzene ring is 55.08 (6)°. One of the azide N atoms is disordered over two positions in a 0.65 (2):0.35 (2) ratio. In the crystal, aromatic π–π stacking is observed [minimum centroid–centroid separation = 3.6499 (13) Å] as well as inversion-dimers connected by pairs of weak C—H...π inter­actions.

In the title compound, C17H14BrNO3S, the phenyl ring makes a dihedral angle of 89.78 (16)° with the plane of the indole ring system. The terminal Br atom and the methyl group are disordered over two sets of sites, with site occupancies of 0.860 (2) and 0.140 (2). In the crystal, mol­ecules are linked into a chain along the b-axis direction by weak C—H...O hydrogen bonds. The chains are further linked by C—H...π inter­actions, forming layers parallel to the bc plane.

In the title molecular salt, C6H6N3+·C7H7O3S, the components are linked by N—H...O hydrogen bonds into zigzag chains along [100]. These chains are further connected by weak C—H...O, C—H...π and π–π (centroid-to-centroid distances = 3.510, 3.701 and 3.754 Å) inter­actions into a three-dimensional network.

In the anion of the title salt, C2H6NO2+·C7H5O6S, the dihedral angle between the carb­oxy­lic acid group and the benzene ring is 5.02 (12)°. In the crystal, the anions are linked into inversion dimers through pairs of O—H...O hydrogen bonds between the carb­oxy­lic acid groups and sulfonate O atoms. A pair of C—H...O inter­actions is also observed within each dimer. The anion dimers and the cations are linked into a three-dimensional network by N—H...O, O—H...O and C—H...O hydrogen bonds.
