J. Wang et al., A SUBSTITUTED CIS,TRANS,CIS,CIS[4.5.5.5]FENESTRENE, Acta crystallographica. Section C, Crystal structure communications, 52, 1996, pp. 2311-2313
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.
