2-Hydr­oxy-3-nitro-N-phenyl­benzamide

The asymmetric unit of the title compound, C(13)H(10)N(2)O(4), contains two crystallographically independent mol­ecules. The aromatic rings are oriented at dihedral angles of 24.39 (3) and 7.47 (3)° in the two mol­ecules and intra­molecular N—H⋯O and O—H⋯O hydrogen bonds result in the formation of two planar six-membered rings. In the crystal structure, inter­molecular O—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into chains, forming R (2) (2)(10) ring motifs. Weak π–π contacts between the benzene and phenyl rings [centroid–centroid distance = 3.955 (3) Å] may further stabilize the structure.
