Meaning of pancake bond | Babel Free

Definitions

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.

Examples

“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.”
