The asymmetric unit of the title compound, C(14)H(12)N(2)O(4), contains two mol-ecules that differ principally in the orientation of the acetamide substituent to the adjacent benzene ring with dihedral angles of 44.77 (7) and 19.06 (7)°. The dihedral angles between the benzene rings are 64.46 (4) and 80.84 (4)°. In the crystal, classical N-H⋯O hydrogen bonds form C(4) chains along [100]. These chains are inter-linked by C-H⋯O contacts forming R(2) (2)(10) rings. In the crystal, π-π inter-actions are observed with a distance of 3.5976 (18) Å between the centroids of the nitro-substituted benzene rings of one type of mol-ecule. |
