However, it should be noted that the number of intramolecular hydrogen bonds is generally very low in all cases. Altogether, these results indicate that the MMG-6 molecules form more stable structures due to intermolecular hydrogen bonding, which would, in turn, increase the energetic cost of interdigitation. To further elucidate hydrogen bonding behavior in our systems, we computed the hydrogen bond ACFs from overall direct hydrogen bonding (intraand intermolecular combined); the results for this analysis can be found in Figure .12.
