The title compound, C(13)H(11)N(3)O(3), is essentially planar (r.m.s. for the 19 non-H atoms = 0.031 Å), a conformation stabilized in part by intra-molecular O-H⋯N and N-H⋯O hydrogen bonds. The configuration about the imine bond [1.2919 (12) Å] is E. The presence of N-H⋯O(nitro) hydrogen bonds leads to the formation of supra-molecular tapes in the crystal structure. These are connected into layers by π-π inter-actions [centroid-centroid distance = 3.6046 (6) Å] occurring between the hy-droxy- an ...[more]
