Abstract: The title compound, C11H8O5, features a `skipped' diene, an anti-bis(epoxide) and a cyclic carbonate, all embedded in a densely functionalized [4.4.3]propellane scaffold. The crystal packing of this diepoxide is effected primarily by C-HO hydrogen bonds, which link the molecules into tapes along the b axis. Inter-tape connectivity is brought about by centrosymmetrically disposed pairs of CO contacts [3.183 (4) Å] between the C+=O- dipoles of neighbouring carbonate moieties.
