The molecule of the title compound, C15H12N2O2, displays a trans configuration with respect to the C=N double bond. The dihedral angle between the two benzene rings is 30.46 (14)°. A strong intramolecular O—H⋯O hydrogen bond stabilizes the molecular structure.

3-Aminobenzonitrile (0.59 g, 5 mmol) and 2-hydroxynaphthalene-1-carbaldehyde (0.760 g, 5 mmol) were dissolved in ethanol (25 ml). The resulting mixture was heated to reflux for 5 h, then cooled to room temperature. The solid obtained product was collected by filtration. Crystals suitable for X-ray diffraction studies were obtained on slow evaporation of the solvent at room temperature.
All H atoms were located geometrically and treated as riding atoms, with O—H = 0.82 Å, C—H = 0.93-0.96 Å, and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C, O) for hydroxy and methyl H atoms. Due to lack of significant
effects, Friedel pairs were merged.Data collection: SMART (Bruker, 2000); cell

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. |

Schiff base compounds have received considerable attention for many years because these compounds play important role in coordination chemistry related to magnetism (Weber, et al., 2007) and biological process (May, et al.,2004). Our group is interested in the synthesis and characterization of Schiff base ligands. Here, we report the synthesis and crystal structure of the title compound.
The molecular structure of the title compound is shown in Fig. 1. The molecule displays a trans configuration about the central C=N double bond and adopts the phenol–imine tautomeric form, with a strong intramolecular O—H···O hydrogen bond (Table 1). Bond lengths (Allen et al., 1987) and angles are within normal ranges. The dihedral angle between two benzene rings is 30.46 (14)°. The crystal packing is stabilized only by van der Waals interactions.
