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 hydrogenbon
The title compound, C 32 H 28 O 4 , crystallizes with two conformers, and , in the asymmetric unit. In both conformers, the benzoyl and methoxyphenyl groups are in cis positions. The cyclobutane rings are puckered, with average absolute torsion angles of 10.8 (2) and 11.4 (1) for conformers and , re
