The title hydrazone compound, C15H14N2O2, was prepared by the condensation of 4-hydroxybenzaldehyde with 2-methylbenzohydrazide in methanol. The dihedral angle between the two benzene rings is 42.3 (2)°. In the molecules are linked by intermolecular O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds, forming a three-dimensional framework.

4-Hydroxybenzaldehyde (0.1 mmol, 12.2 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 colourless solution. Colourless block-shaped crystals of the compound were formed by slow evaporation of the solvent over several days.
Atom H2 was located in a difference Fourier map and refined isotropically, with the N–H distance restrained to 0.90 (1) Å [Uiso(H) = 0.08 Å2]. Other H atoms were constrained to ideal geometries, with C–H = 0.93–0.96 Å, O–H = 0.82 Å, and with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(C15 and O1). In the absence of significant
effects, Friedel pairs were averaged.Data collection: SMART (Bruker, 2002); cell

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 been received much attention in biological chemistry 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). In the present paper, the author reports the crystal structure of the title new hydrazone compound (Fig. 1).
In the title molecule, the dihedral angle between the two benzene rings is 42.3 (2)°. The torsion angles C1—C7—N1—N2, C7—N1—N2—C8 and N1—N2—C8—C9 are 2.9 (2), 0.9 (2), and 0.2 (2)°, respectively. All the bond lengths are within normal values (Allen et al., 1987).
In the crystal structure of the compound, molecules are linked through O–H···O, O–H···N, and N–H···O intermolecular hydrogen bonds (Table 1), forming a three-dimensional network (Fig. 2).
