title: N-(2,3-Dimethyl-phen-yl)-4-fluoro-N-[(4-fluoro-phen-yl)sulfon-yl]benzene-sulfonamide.
abstract: In the title compound, C(20)H(17)F(2)NO(4)S(2), the dihedral angles between the o-xylene ring and the fluoro-benzene rings are 31.7 (1) and 32.8 (1)°, and the dihedral angle between the fluoro-benzene rings is 50.9 (1)°. The C-N-S-C torsion angles are 76.7 (2) and 101.8 (2)°. In the crystal, mol-ecules are connected by C-H⋯O inter-actions into sheets in the ab plane.
