✦ Synopsis

Molecules of the title compound, C 34 H 24 Cl 2 O 6 , lie across crystallographic inversion centres. The ¯avone 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 CÐHÁ Á ÁCl hydrogenbonded dimers. The structure is further stabilized by van der Waals interactions.
