In the title compound, C26H24Cl4N 2O4S2, the dihedral angles between the central benzene ring and the pendant rings are 70.07 (12) and 59.07 (12)°. The equivalent angle between the pendant rings is 79.24 (12)°. Both sulfonamide groups lie to the same side of the central ring but the pendant chains have very different conformations, as indicated by their C-S-N-C torsion angles [104.66 (17) and -76.35 (19)°] and S-N-C-C torsion angles [129.61 (17) and 147.10 (17)°]. Both N atoms are close to planar (bond angle sums = 359.0 and 354.8°). In the crystal, inversion dimers are formed via a pair of weak C-H⋯O interactions which generate R2 2(22) loops.
