Abstract
The title compound, clo[5.4.1.O-4,O-12.O-9,O-12]dodec-10-enyl-1-acetic acid, C14H18O2, has been prepared and its structure elucidated. The g eometry of the central C(C)(4) substructure shows a considerable disto rtion from an ideal tetrahedral arrangement towards planarity, with tw o opposite bond angles of 119.2(2) and 134.9(2)degrees. The other brid gehead bond angle of the trans-bicyclo[3.3.0]octane subunit is also la rge, with a value of 128.0(2)degrees.
