In the title compound, C25H15FN2O6S, the carbazole ring system is essentially planar, with a maximum deviation of 0.1534 (16) Å for the C atom connected to the 4-fluoro-2-nitrophenyl ring. It is almost orthogonal to the phenylsulfonyl and nitrophenyl rings, making dihedral angles of 88.45 (8) and 79.26 (7)°, respectively. The molecular structure is stabilized by O—H...O and C—H...O hydrogen bonds, which generate three S(6) ring motifs. In the crystal, molecules are linked by two C—H...O hydrogen bonds, which generate C(6) and C(9) chains running in the [100] and [010] directions, respectively, so forming a two-dimensional network lying parallel to (001). There are also supramolecular R43(28) graph-set ring motifs enclosed within these networks
