In the title compound, C13H10FNO, the benzene ring planes are inclined at an angle of 50.52 (8)°. A characteristic of aromatic Schiff bases withN-aryl substituents is that the terminal phenyl rings are twisted relative to the plane of the HC=N link between them. In this case, the HC=N unit makes dihedral angles of 10.6 (2) and 40.5 (2)° with the hydroxybenzene and flurobenzene rings, respectively. In the crystal, O—H...N and C—H...F hydrogen bonds lead to the formation of chains along thec-andb-axis directions, respectively. C—H...π contacts link molecules alongaand these contacts combine to generate a three-dimensional network with molecules stacked along theb-axis direction.
