2-Hy­droxy-N-(3-nitro­phen­yl)benzamide

In the crystal structure of title compound, C(13)H(10)N(2)O(4), as expected, the nitro- and hy­droxy-substituted benzene rings are planar with r. m. s. deviations of 0.0037 and 0.0014 Å, respectively, but are twisted slightly relative to each other, making a dihedral angle of 12.23 (7)°. The nitro group is only slightly twisted [by 2.71 (16)°] with respect to its parent ring. An intra­molecular N—H⋯O hydrogen bond forms an S(6) ring motif. Inter­molecular N—H⋯O and O—H⋯O hydrogen bonds build up sheets parallel to the ab plane. Futhermore, weak π–π inter­actions [centroid–centroid distances = 3.7150 (8) 3.7342 (6) and 3.9421 (8) Å] between the rings yield a three-dimensional network.
