The asymmetric unit of the title compound, C H N O , contains two independent mol-ecules ( and ). The two benzene rings are twisted by an angle of 79.14 (7)° in mol-ecule , whereas, in mol-ecule , they are inclined by 19.02 (14)°. The conformations of the mol-ecules are stabilized by intra-molecular N-H⋯O hydrogen bonds between the amide nitro-gen atom and the O atom of the -nitro substituent on the phenyl ring, enclosing an (6) ring motif. In the amide and aliphatic segments, all the N-H, C=O and C-H bonds are to each other. In the crystal, the and mol-ecules are linked by inter-molecular amide-to-amide N-H⋯O hydrogen bonds, resulting in chains running along the axis direction. The inter-molecular inter-actions were analysed using Hirshfeld surface analysis. The two-dimensional fingerprint plots of the inter-molecular contacts indicate that the major contributions are from H⋯H and O⋯H inter-actions.
