Abstract

The title compound, C₁₈H₁₂N₂O, crystallizes in a phenol–imine tautomeric form with a Z conformation for the imine functionality. The dihedral angle between the aromatic rings is 8.98 (9)°. A strong intramolecular O—H⋯N hydrogen-bond interaction between the hydroxyl group and imine N atom occurs.

Comment

Schiff base compounds have received considerable attention for many years because these compounds play an important role in coordination chemistry related to magnetism (Weber et al., 2007) and catalysis (Chen et al., 2008).Our group is interested in the synthesis and preparation of Schiff bases. Here, we report the synthesis and crystal structure of the title compound.

Figure 1 shows an ORTEP plot of the title compound. The molecule adopts the phenol–imine tautomeric form with a strong intramolecular O—H···N hydrogen bond. The C11N1 and C2—O1 bond lengths [1.296 (3) and 1.324 (3) Å, respectively] are comparable to corresponding values observed in a similar phenol–imine tautomeric structures (e.g. Petek et al., 2007), while different geometry is observed in the case of zwitterionic molecules (Elmali et al., 2001; Yüce et al., 2006). Phenyl and naphthalyl rings, A (C12···C17) and B (C1···C10), are, of course, planar, and the dihedral angle between them is 8.98 (9)°. The molecule displays a trans configuration about the central CN imine bond. Molecules are packed in the crystal at van der Waals distances.

Experimental

2-Aminobenzonitrile (0.59 g, 5 mmol) and 2-hydroxynaphthalene-1-carbaldehyde (0.861 g, 5 mmol) were dissolved in ethanol (25 ml). The resulting mixture was refluxed for 5 h and cooled to room temperature. The solid product was collected by filtration. Crystals suitable for X-ray diffraction studies were obtained on slow evaporation at room temperature.
