The title nitro-phenyl benzamide, C13H9BrN2O3, with two mol-ecules in the asymmetric unit, has dihedral angles of 16.78 (15) and 18.87 (14)° between the benzene rings. An intra-molecular N-H⋯O hydrogen bond is observed in each mol-ecule. In the crystal, the molecules are linked by weak C-H⋯O inter-actions; halogen-halogen inter-actions are also observed [Br⋯Br = 3.4976 (7) Å]. These inter-actions form R (2) 2(10), R (2) 2(15) and R (6) 6(32) edge-fused rings along [010].
标题化合物硝基苯基苯甲酰胺（C₁₃H₉BrN₂O₃），其不对称单元中有两个分子，苯环之间的二面角分别为16.78 (15)°和18.87 (14)°。在每个分子中均观察到分子内N-H⋯O氢键。在晶体中，分子通过弱C-H⋯O相互作用相连；还观察到卤-卤相互作用[Br⋯Br = 3.4976 (7) Å]。这些相互作用沿着[010]形成R (2) 2(10)、R (2) 2(15)和R (6) 6(32)边稠合环。
