The title compound, C23H18N2O4S2, 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 – interactions [centroid–centroid distances = 3.6258 (8) and 3.9298 (8) A ̊ ], which contribute to the stability of the packing.
