In the title compound, C(13)H(8)ClN(3)O(5), the dihedral angle between the two aromatic rings is 70.74 (6)°. The nitro groups of the Cl-substituted and benzamide benzene rings are twisted by 2.6 (1) and 31.3 (2)°, respectively. The crystal packing shows inter-molecular C-H⋯O hydrogen bonds that link mol-ecules into sheets stacked along [010].

In the crystal structure of the title compound, C(13)H(11)Cl(2)NO(2)S, the conformations of the N-C bond in the C-SO(2)-NH-C segment are trans and gauche with respect to the S=O bonds. The C-S(O(2))-N(H)-C torsion angle is 74.8 (4)°, indicating that the mol-ecule is bent at the S atom. In the crystal structure, inversion dimers linked by pairs of N-H⋯O hydrogen bonds occur. An intramolecular N-...
