Abstract: Molecules of the title compound, C₃₄H₂₄Cl₂O₆, lie across crystallographic inversion centres. The flavone moiety is slightly folded, with the benzene and dihydropyrone rings making a dihedral angle of 2.5  (2)°. In the crystal, the molecules exist as cyclic intermolecular C-HCl hydrogen-bonded dimers. The structure is further stabilized by van der Waals interactions.
