5,6-Dimethyl-1,2,9,10-tetrahydropyrano[3,2-f]chromene-3,8-dione

The title molecule, C(14)H(14)O(4), lies on a twofold rotation axis that bisects the central benzene ring, with only one half-molecule in the asymmetric unit. The pyranone systems adopt distorted twist- boat conformations, with the two methylene C atoms displaced by 0.537 (1) and 0.163 (2) Å fr...
