bi- +‎ cyclic

- 2003, Journal of the American Chemical Society‎, volume 125, page 134:
  […] substitution of a carboxylate would be expected to destabilize the dritterionic mesomer that contributes to the singlet valence bond description as the benzyne geometry becomes more bicyclic.
- 2006, PJ Fazen, LA Burke, “Theoretical studies of borazynes and azaborines”, in Inorganic chemistry:
  These geometries are almost reversed in the triplets. The 1,3-borazyne (III) shows more bicyclic character than the corresponding m-benzyne
- 2007, S Venkataramani, M Winkler, “Trifluoro‐1, 3, 5‐tridehydrobenzene”, in Angewandte Chemie:
  On the basis of a comparison of calculated and measured IR data, the 2 B 2 state could undoubtedly be discarded in favor of a more bicyclic geometry
