Abstract
The title compound, C13H10INO, is not planar as the dihedral angle between the planes of the two aryl rings is 44.5 (9)°. The configuration about the central C=N bond is E, and there is an intramolecular O—H...N hydrogen bond which generates an S(6) ring. The molecular packing is stabilized by weak C—H...π interactions. The structure was refined as a two-component inversion twin.

Abstract
The title compound, C14H13NO, is not planar with the dihedral angle between the planes of the two aryl rings being 6.22 (11)°. The configuration about the imine bond isE. An intramolecular O—H...N hydrogen bond generates anS(6) loop. In the crystal, molecules assemble into columns parallel to theaaxis. The methyl group is disordered over two positions rotated from each other by 60°.

Abstract
The title compound, C13H10FNO, is essentially planar (r.m.s. deviation = 0.022 Å) and the dihedral angle between the planes of the two aryl rings is 0.69 (15)°. An intramolecular O—H...N hydrogen bond generates anS(6) ring. The crystal structure features C—H...O hydrogen bonds.
