In the title compound, C13H10N4O5·0.5C2H5OH, the two benzene rings form a dihedral angle of 4.29 (9)°. The ethanol solvent molecule was treated as disordered between two orientations related by symmetry (center of inversion), with occupancies fixed at 0.5. The crystal packing, stabilized by intermolecular O—H⋯O and N—H⋯O hydrogen bonds and π–π interactions [indicated by the short distance of 3.7299 (7) Å between the centroids of benzene rings from neighbouring molecules], exhibits short intermolecular O⋯O contacts of 2.8226 (3) Å.

The title compound was synthesized by the reaction of (2,4-dinitro-phenyl)-hydrazine (1 mmol, 198.1 mg) with 4-hydroxy-benzaldehyde (1 mmol, 122.1 mg) in ethanol (20 ml) under reflux conditions (338 K) for 4 h. The solvent was removed and the solid product recrystallized from ethanol. After five days brown crystals were obtained that were suitable for X-ray diffraction study.
All H atoms were placed in idealized positions (C—H = 0.93–0.97 Å, N—H = 0.86 Å) and refined as riding atoms. For those bound to C, Uiso(H) = 1.2 or 1.5Ueq(C). while for those bound to N, Uiso(H) = 1.2 Ueq(N). The ethanol solvent molecule has been treated as disordered between two orientations related by symmetry (center of inversion) with occupancies fixed to 0.5 and with C—O, C—C and O···C distances restrained to 1.40 (1), 1.45 (1) and 2.40 (1) Å, respectively.
As a contribution to structural studies of 2,4-dinitrophenylhydrazones (Baughman et al., 2004; Shi et al., 2008; Ji et al., 2008;) we present here the
of the title compound (I).In (I) (Fig. 1), all bond lengths and angles are normal (Allen et al., 1987). The crystal packing, stabilized by intermolecular O—H···O and N—H···O hydrogen bonds (Table 1) and π–π interactions proved by short distance of 3.7299 (7) Å between the centroids of benzene rings from the neighbouring molecules, exhibits short intermolecular O···O contacts of 2.8226 (3) Å.

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. |

As a contribution to structural studies of 2,4-dinitrophenylhydrazones (Baughman et al., 2004; Shi et al., 2008; Ji et al., 2008;) we present here the crystal structure of the title compound (I).
In (I) (Fig. 1), all bond lengths and angles are normal (Allen et al., 1987). The crystal packing, stabilized by intermolecular O—H···O and N—H···O hydrogen bonds (Table 1) and π–π interactions proved by short distance of 3.7299 (7) Å between the centroids of benzene rings from the neighbouring molecules, exhibits short intermolecular O···O contacts of 2.8226 (3) Å.
