In the title compound, C23H19NO4S2, the indole ring system makes dihedral angles of 89.6 (1) and 84.5 (8)° with the phenylsulfonyl and phenylsulfanyl rings, respectively. In the crystal, the molecules are linked into C(10) chains running along the c axis by an intermolecular C—H⋯O hydrogen bond. In addition, the crystal packing is stabilized by C—H⋯π interactions.
