And Chemical Properties

The crystal structure of single-layer graphene in comparison to graphite is discussed with regard to its crystallographic and chemical properties. In both of these polymorphs of carbon, the atomic volume of carbon, reduced to the closest packing of atoms, is practically the same and considerably smaller than in diamond. This indicates pentavalent carbon in graphene as well as in graphite. The observed elastic corrugations of the graphene layers which probably cause their amazing rigidity seem to be due to numerous weak chemical bonds within the layers.

AbstractFundamentals of a bond length based crystal chemistry which emerges from the bond valence method and goes beyond the concept of ionic radii are discussed. In many cases, atomic distances can serve as a measure of chemical bonding. Unobserved interatomic distances and ionic radii can be predicted from bond-length – bond-strength relationships. Electrical conductivity appears to be connected with peculiarities of bondlengths. The oxidizing power of oxides and oxo-complexes seems to be correlated with oxygen bond-lengths. Secondary bonds and intermolecular interactions appear as weak chemical bonds.
