pancake bond
noun1
Chemistry, Natural sciences, Physical sciences A type of chemical bond most prominently observed in polycyclic hydrocarbons, in which the nuclear distance between molecular constituents reaches or exceeds a bond length of approximately 305 pm.
- Unusually long bonds or short intermolecular contacts occur in the title compounds reminiscent of pancake bonding. Pancake bonding interactions seem analogous to π-stacking interactions, but they display much shorter contact distances than normally seen in van der Waals (vdW) dimers.2012, Habtamu Z.
