3D-graphite structure

The structure of clusters of some new carbon 3D-graphite phases have been calculated using the molecular-mechanics methods. It is established that 3D-graphite polytypes α_{1, 1}, α_{1, 3}, α_{1, 5}, α_{2, 1}, α_{2, 3}, α_{3, 1}, β_{1, 2}, β_{1, 4}, β_{1, 6}, β_{2, 1}, and β_{3, 2} consist of sp ²-hybridized atoms, have hexagonal unit cells, and differ in regards to the structure of layers and order of their alternation. A possible way to experimentally synthesize new carbon phases is proposed: the polymerization and carbonization of hydrocarbon molecules.
