Cover illustration: The 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-H...O hydrogen bonds, which link the mol­ecules into tapes along the b-axis direction. Inter-tape connectivity is brought about by centrosymmetrically disposed pairs of C...O contacts [3.183 (4) Å] between the C[delta]+=O[delta]- dipoles of neighbouring carbonate moieties.
