The title compound, C14H11N3O5, is essentially planar, with an r.m.s. deviation for the non-H atoms of 0.0832 (3) Å. In the crystal, O—H⋯O and N—H⋯O hydrogen bonds link adjacent molecules into layers parallel to (101). These layers are further connected into a three-dimensional network via C—H⋯O interactions. In addition, a π–π interaction occurs between the aromatic rings [centroid–centroid distance = 3.5425 (8) Å]. An intramolecular O—H⋯N hydrogen bond is also observed.

A mixture of 4-nitrobenzohydrazide (0.54 g, 3 mmol) and 4-hydroxysalicylaldehyde (0.39 g, 3 mmol) in ethanol (50 ml) and in the presence of a few drops of acetic acid was refluxed for 5 hr. The solution was then left at room temperature. The crystals of the title compound were obtained in a few days.
The carbon-bound H atoms were placed at calculated positions (C—H = 0.95 Å) and treated as riding on their parent carbon atoms. The nitrogen- and oxygen-bound H atoms were located in a difference map and refined as free atoms, with N—H and O—H distances restrained to 0.88 (2) and 0.84 (2) Å, respectively. Uiso(H) values were set to 1.2–1.5 Ueq(carrier atom).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound is the product of the condensation reaction of 4-nitrobenzohydrazide and 4-hydroxysalicylaldehyde. In agreement with the structures of similar benzoylhydrazones (Han & Zhao, 2010; Mohd Lair et al., 2009; Raj et al., 2008), the molecular structure of the present molecule is almost planar, the r.m.s. deviation for the non-H atoms being 0.0832 Å. The crystal structure is stabilized by O—H···O, N—H···O and C—H···O intermolecular and also O—H···N intramolecular hydrogen bonding. Moreover, a π–π interaction occurs between the aromatic rings of pairs of molecules related by symmetry -x, -y + 1, -z + 2 with centroid-centroid separation of 3.5425 (8) Å.
