4-Phenyl­sulfon­yl-2-(p-tolyl­sulfon­yl)-1H,8H-pyrrolo­[2,3-b]indole

The title compound, C(23)H(18)N(2)O(4)S(2), contains a pyrrolo group fused onto the plane of an indole ring with phenyl­sulfonyl and p-toluene­sulfonyl groups bonded to the indole and pyrrolo rings. The angles between the mean planes of the pyrrolo-indole ring and the phenyl­sulfonyl and p-toluene­sulfonyl rings are 73.7 (6) and 80.6 (0)°, respectively. The dihedral angle between the mean planes of the two benzene rings is 78.7 (4)°. In the crystal, both classical N—H⋯O and non-classical C—H⋯O inter­molecular hydrogen-bonding inter­actions are observed, as well as weak π–π inter­actions [centroid–centroid distances = 3.6258 (8) and 3.9298 (8) Å], which contribute to the stability of the packing.
