In the title compound, C16H12F2O3, the plane of the phenyl ring makes a dihedral angle of 3.22 (8)° with that of the benzene ring. The molecule has an E conformation about the C=C bond. In the crystal, molecules are linked via pairs of O—HO hydrogen bonds, forming inversion dimers which are further consolidated by a pair of C—HO hydrogen bonds. The dimers are linked via C—HO hydrogen bonds, forming columns along the b-axis direction.

In the title compound, C26H22ClFO2, the cyclopropane ring is disordered over two orientations, with site-occupancy factors of 0.64 (2) and 0.36 (2). The major occupancy component of the cyclopropane ring makes dihedral angles of 47.6 (7), 50.4 (7) and 65.4 (7)° with the fluoro-, chloro- and unsubstituted benzene rings, respectively [the corresponding values for the minor occupancy component are 47.6 (12), 51.0 (12) and 60.9 (12)°]. An intramolecular C—HO hydrogen bond occurs. The F and Cl atoms deviate by 0.0508 (12) and 0.0592 (7) Å from the planes of their attached benzene rings. In the crystal, C—HF hydrogen bonds link the molecules into chains along the b-axis direction.
