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].
