(2Z,4E)-1-(5-Fluoro-2-hydroxyphenyl)-5-(4-fluorophenyl)-3-hydroxypenta-2,4-dien-1-one

Abstract

In the title molecule, C17H12F2O3, the dihedral angle between the benzene rings is 8.6 (2)°. In the crystal, two pairs of O—H...O hydrogen bonds connect the molecules into inversion dimers. In addition, weak C—H...F hydrogen bonds link the dimers into a two-dimensional network parallel to (10-4). The carbonyl O atom is an acceptor for two weak intramolecular hydrogen bonds.
