In the title mol-ecule, C(13)H(8)N(4)O(7), the amide fragment has an anti configuration. The mean planes of the two benzene rings form a dihedral angle of 7.78 (4)°. The mean planes of the three nitro groups are twisted by 6.82 (3), 5.01 (4) and 18.94 (7)° with respect to the benzene rings to which they are attached. In the crystal, mol-ecules are linked by weak inter-molecular N-H⋯O hydrogen bonds into chains along [100].
