Crystal structure of 6,6′-dimethyl-2H,2′H-3,4′-bichromene-2,2′-dione

In the title compound, C20H14O4, the dihedral angle between the two coumarin ring systems is 52.37 (19)°, showing a gauche arrangement across the C—C bond which links the two units. The carbonyl groups of the two coumarin units adopt an s-trans arrangement. In the crystal, pairs of C—H...O hydrogen...
