3-Bromo-methyl-4-meth-oxy-2-(2-nitro-phen-yl)-9-phenyl-sulfonyl-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 nitro-phenyl group. The carbazole moiety is almost orthogonal to the benzene rings of the adjacent phenyl-sulfonyl and nitro-phenyl groups, making dihedral angles of 85.43 (15) and 88.62 (12)°, respectively. The mol-ecular conformation is stabilized by two C-H⋯O hydrogen bonds involving the sulfone group, which form similar six-membered rings. In the crystal, mol-ecules 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 inter-actions.
