Abstract: The title compound, 6,6-(3,6-diprop-2-enylpentacyclo[6.2.1.0^2,7.0^4,10.0^5,9]undecane-3,6-diyldioxy)pentacyclo[6.2.1.0^2,7.0^4,10.0^5,9]undecan-3-one, C₂₈H₃₀O₃, is a pentacycloundecane dimer. The molecule is chiral and contains two polycyclic pentacycloundecane cage units. Both enantiomers are present in the crystal structure. In the molecule, certain C-C bond lengths deviate from the normal value, with both short and long bonds present.
