In the title hydrated zwitterion, C11H13NO3S2·H2O, the N—C—C—C and C—C—C—S torsion angles in the side-chain are 171.06 (14) and 173.73 (12)°, respectively. In the crystal, inversion-related molecules are π-stacked with an interplanar separation of 3.3847 (2) Å. O—H
O hydrogen bonds link inversion-related molecules with a pair of water molecules to form R42(8) rings. The closest SS contact is 3.4051 (15) Å between inversion-related molecules.

In the title compound, C21H23NO2, the hexyl group adopts an extended conformation, the six C atoms are nearly coplanar [maximum deviation = 0.082 (3) Å] and their mean plane is approximately perpendicular to the carbazole ring system, with a dihedral angle of 78.91 (15)°. In the crystal, molecules are linked by O—HO hydrogen bonds, forming inversion dimers; π–π stacking between carbazole ring systems of adjacent dimers further links the dimers into supramolecular chains propagating along the b-axis direction [centroid-to-centroid distances = 3.868 (2) and 3.929 (2) Å].
