Considering IGM surfaces size, there is some correspondence with the Eads tendency since C5-G, C6-G, and C7-G hybrids are the more stable systems. The latter can be explained considering that the sum of an extended number of low stabilizing interactions achieves a valuable contribution to the whole stabilization. This point suggests that the dispersion forces are presumably the driving forces for the interaction of C-G hybrids, considering the πstacking prevalence in all the current studied hybrids.
