In the title compound, C21H18O2SSe, the dihedral angle between the cis phenyl rings is 64.3 (1)° and those between the toluene and the phenyl rings are 21.1 (2) and 72.0 (1)°, respectively. An intra­molecular Se—H⋯O hydrogen bond occurs. In the crystal, mol­ecules are connected by C—H⋯O hydrogen bonds and weak C—H⋯π inter­actions help to consolidate the crystal packing.
