- (not-comparable) Having two cycles.
-
(not-comparable) Having two rings of atoms in the molecule; the rings may be fused, as in naphthalene, or separate, as in biphenyl.
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
2007, S Venkataramani, M Winkler, “Trifluoro‐1, 3, 5‐tridehydrobenzene”, in Angewandte Chemie, Wiley Online Library:[…] 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.
2003, Journal of the American Chemical Society, volume 125, page 134:These geometries are almost reversed in the triplets. The 1,3-borazyne (III) shows more bicyclic character than the corresponding m-benzyne
