Abstract
The title Schiff base compound, 0.57C17H12FNO·0.43C17H12FNO, reveals both the enol (OH) and keto (NH) tautomeric forms with occupancies of 0.57 (6) and 0.43 (6), respectively. The tautomeric forms are stabilized by intramolecular O—H...N (enol) and N—H...O (keto) hydrogen bonds. The dihedral angle between the naphthalene ring system and the benzene ring is 32.76 (1)°.
