The title hydrazone compound, C15H13N3O3·CH3OH, crystallized as a methanol solvate. The hydrazone molecule has an E configuration about the C=N bond and is almost planar, with a dihedral angle between the benzene rings of 5.3 (3)°. In the crystal, the hydrazone molecules are linked via the methanol solvent molecule through N—H⋯O and O—H⋯O hydrogen bonds, so forming chains propagating along the a-axis direction.

4-Nitrobenzaldehyde (0.1 mmol, 15.1 mg) and 3-methylbenzohydrazide (0.1 mmol, 15.0 mg) were dissolved in methanol (20 ml). The mixture was stirred at reflux for 10 min to give a clear yellow solution. Yellow needle-shaped crystals of the compound were formed by slow evaporation of the solvent over several days.
The amino H atom was located in a difference Fourier map and was refined with the N—H distance restrained to 0.90 (1) Å. Other H atoms were constrained to ideal geometries and refined as riding atoms: O—H = 0.82 Å, Csp2—H = 0.93 Å, and C(methyl)—H = 0.96 Å, with Uiso(H) = k × Ueq(parent C or O-atom), where k = 1.5 for OH and CH3 H-atoms and k = 1.2 for all other H-atoms.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Hydrazone compounds have received much attention in biological and structural chemistry in the last few years (Rasras et al., 2010; Pyta et al., 2010; Angelusiu et al., 2010; Fun et al., 2008; Singh & Singh, 2010; Ahmad et al., 2010). As a continuation of our work on the structural study of such compounds (Tang, 2010, 2011), the author reports herein the crystal structure of the new title hydrazone compound.
The title hydrazone molecule crystallized as a methanol solvate (Fig. 1). The methanol molecule is linked to the hydrazone molecule through an intermolecular O4—H4···O3 hydrogen bond (Fig. 1, Table 1). In the hydrazone molecule the dihedral angle between the two benzene rings is 5.3 (3)°. Bond lengths in the compound are normal (Allen et al., 1987) and comparable to those in the similar compounds referred to above.
In the crystal, the hydrazone and methanol molecules are linked via the methanol molecule, through intermolecular N—H···O and O—H···O hydrogen bonds (Table 1), forming chains along the a axis (Fig. 2).
