In the crystal structure of title compound, C(13)H(10)N(2)O(4), as expected, the nitro- and hy-droxy-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 intra-molecular N-H⋯O hydrogen bond forms an S(6) ring motif. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds build up ...[more]
