The whole molecule of the title compound, C20H19NO4S2, is generated by twofold rotational symmetry. The N atom is located on the twofold rotation axis and has a trigonal-planar geometry. It is bonded by two S atoms of two symmetry-related 4-methylphenylsulfonyl groups and by the C atom of the phenyl ring, which is bisected by the twofold rotation axis. The benzene and phenyl rings are oriented at a dihedral angle of 51.48 (5)degrees while the pendant benzene rings are inclined to one another by 87.76 (9) degrees. In the crystal, weak C-H center dot center dot center dot O hydrogen bonds link the molecules, forming a three-dimensional network.
