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—Hπ 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—HO hydrogen bonds. The chains are further linked by C—Hπ interactions, forming layers parallel to the bc plane.

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—HO hydrogen bonds between the carboxylic acid groups and sulfonate O atoms. A pair of C—HO interactions is also observed within each dimer. The anion dimers and the cations are linked into a three-dimensional network by N—HO, O—HO and C—HO hydrogen bonds.
