The title compound, C14H11N3O4, was prepared by the reaction of 4-nitrobenzohydrazide with 4-hydroxybenzaldehyde. The whole molecule of the compound is approximately planar, with a mean deviation from the least-squares plane through all the non-H atoms of 0.050 (2) Å; the dihedral angle between the two benzene rings is 2.0 (2)°. In the crystal, the benzohydrazide molecules are linked through intermolecular O—H⋯O and N—H⋯O hydrogen bonds, forming layers in the bc plane.

The reaction of 4-nitrobenzohydrazide (0.181 g, 1 mmol) with 4-hydroxybenzaldehyde (0.122 g, 1 mmol) in 50 ml methanol at room temperature afforded the title compound. Single crystals were formed by slow evaporation of the clear solution in air.
The amino H atom was located in a difference Fourier map and refined with N–H = 0.90 (1) Å, and Uiso = 0.08 Å2. Other H atoms were positioned geometrically (C–H = 0.93 Å, O–H = 0.82 Å) and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.5 Ueq(O).
Recently, medical applications of a number of hydrazone compounds have been reported (Ajani et al., 2010; Zhang et al., 2010; Angelusiu et al., 2010). Structural investigations of several hydrazone derivatives have also been determined (Huang & Wu, 2010; Khaledi et al., 2010; Zhou & Yang, 2010; Ji & Lu, 2010; Singh & Singh, 2010; Ahmad et al., 2010). In this paper, we report the structure of the new derivative N'-(4-Hydroxybenzylidene)-4-nitrobenzohydrazide (I).
The whole molecule of (I) is approximately planar, with a mean deviation from the least squares plane through all 21 non-hydrogen atoms of 0.050 (2) Å; the dihedral angle between the C1···C6 and C9···C14 benzene rings is 2.0 (2)°. The bond lengths and angles are comparable to those found in the hydrazone compounds cited above. In the
the hydrazone molecules are linked through intermolecular O1–H1···O2 and N2–H2···O4 hydrogen bonds (Table 1), to form two-dimensional layers in the bc plane, as shown in Fig. 2.For medical applications of

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. |

Recently, medical applications of a number of hydrazone compounds have been reported (Ajani et al., 2010; Zhang et al., 2010; Angelusiu et al., 2010). Structural investigations of several hydrazone derivatives have also been determined (Huang & Wu, 2010; Khaledi et al., 2010; Zhou & Yang, 2010; Ji & Lu, 2010; Singh & Singh, 2010; Ahmad et al., 2010). In this paper, we report the structure of the new derivative N'-(4-Hydroxybenzylidene)-4-nitrobenzohydrazide (I).
The whole molecule of (I) is approximately planar, with a mean deviation from the least squares plane through all 21 non-hydrogen atoms of 0.050 (2) Å; the dihedral angle between the C1···C6 and C9···C14 benzene rings is 2.0 (2)°. The bond lengths and angles are comparable to those found in the hydrazone compounds cited above. In the crystal structure, the hydrazone molecules are linked through intermolecular O1–H1···O2 and N2–H2···O4 hydrogen bonds (Table 1), to form two-dimensional layers in the bc plane, as shown in Fig. 2.
