(2E)-3-[4-(Benz­yloxy)phen­yl]-1-(2,6-dichloro-3-fluoro­phen­yl)prop-2-en-1-one

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...π inter­actions are also present.

1,5-Dibromo-2,4-dimeth­oxy­benzene

In the title compound, C₈H₈Br₂O₂, all non-H atoms lie essentially in a common plane (r.m.s deviation of all fitted non-H atoms = 0.0330 Å). In the crystal, weak C—H...O hydrogen bonds connect the mol­ecules, forming chains which extend along the b-axis direction.
