Abstract: In the title compound, C22H15Cl2FO2, a chalcone derivative featuring a threefold-halogenated aromatic substituent, the conformation about the C=C bond is E. In the crystal C-H...F and C-H...Cl contacts connect the molecules into undulating sheets parallel to (101). In addition, C-H...[pi] interactions are also present.
