4-Methyl-N-(4-methyl­phenyl­sulfon­yl)-N-phenyl­benzene­sulfonamide

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)° while the pendant benzene rings are inclined to one another by 87.76 (9)°. In the crystal, weak C—H...O hydrogen bonds link the mol­ecules, forming a three-dimensional network.
