Abstract
A quantum-chemical investigation is performed on the possibility of methane molecule intercalation between graphite-like planes. Ovalene dimer and its clathrates were used as models. We conclude that the existence of inclusion compounds of methane in graphite-like systems is possible. However, these compounds are endothermic, i.e., unstable. It is established that the structure with four methane molecules forms no bound supramolecular system. Clathrates with one, two, and three methane molecules may exist. The most stable of these is the clathrate with methane in the form of a dimer.
