The title mol-ecule, C(14)H(14)Cl(2)N(2)O(4)S(2), lies on an inversion center. The mol-ecule is twisted in the region of the sulfonamide group with a C-S-N-C torsion angle of -67.49 (16)°. In the crystal, mol-ecules are connected via inter-molecular N-H⋯O and weak C-H⋯O hydrogen bonds, forming layers parallel to (100).
