A solution of 4-aminobenzoic acid (5.0 g, 36.5 mmol) in hot ethanol was mixed with an ethanolic solution of 2-hydroxynaphthaldehyde (7.23 g, 36.5 mmol) and the resulting mixture was refluxed for 3 h. The mxiture was cooled to recover the crude product. Orange laths of (I) were recrystalized from ethanol. IR ν (cm-1); 1683.3 (C?O), 1588.1 (C?N), 1427.1 (C?C), 1301.4 (C—O) and 1152 (C—N). [M.p.: > 573 K, yield: 54.7%].
The H atoms were positioned geometrically (C—H = 0.93 Å, O—H = 0.82 Å) and refined as riding with with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(O).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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. |

2-Hydroxy Schiff base ligands and their complexes, derived from the reaction of salicylaldehyde and 2-hydroxy-1-naphthaldehyde with amines are of interest due to the existence of (O—H ···N and N—H ···O) type hydrogen bonds and tautomerism between the enol-imine and keto-enamine forms. Tautomerism in 2-hydroxy Schiff bases both in solution and in the solid state was investigated using different spectroscopic techniques (Asiri & Badahdah, 2007).
In the title compound, (I), the molecule is almost planar (Fig. 1). The maximum deviation of the non-H atoms from their mean plane is 0.087 (1) Å for O3. The dihedral angle between the naphthalene ring and the benzene ring is 4.04 (6)°.
The molecular conformation is stabilized by an intramolecular O—H···N hydrogen bond (Table 1). Then, classical inversion dimers are formed by head-to-head O—H···O linkages of the carboxylic acid groups. Finally, C—H ···O interactions link the dimers into sheets (Fig. 2).
