5-Methyl-12-phenyl-sulfonyl-12H-naphtho-[1,2-b]carbazole.
In the title compound, C(27)H(19)NO(2)S, the naphtho-carbazole unit is approximately planar (r.m.s. deviation = 0.002 Å) except for the N atom, which is displaced by 0.122 (1) Å out of the mean plane. The dihedral angle between the naphtho-carbazole mean plane and the phenyl ring of the phenyl-sulfonyl substituent is 83.16 (3)°. An inter-molecular C-H⋯π inter-action involving the phenyl group and the pyrrole ring is observed in the crystal structure.
