3-Bromomethyl-4-methoxy-2-(2-nitrophenyl)-9-phenylsulfonyl-9H-carbazole

In the title compound, C26H19BrN2O5S, the carbazole tricycle is essentially planar, with the largest deviation being 0.126 (3) Å for the C atom connected to the nitrophenyl group. The carbazole moiety is almost orthogonal to the benzene rings of the adjacent phenylsulfonyl and nitrophenyl groups, making dihedral angles of 85.43 (15) and 88.62 (12)°, respectively. The molecular conformation is stabilized by two C—H...O hydrogen bonds involving the sulfone group, which form similar six-membered rings. In the crystal, molecules symmetrically related by a glide plane are linked in C(6) chains parallel to [001] by C—H...O hydrogen bonds formed with the participation of the nitro group. The chains are reinforced by additional C—H...π interactions.
