Term Name: graphite
Synonyms: black lead, C, Cn, grafito, Graphit, graphite, mineral carbon, plumbago
Definition: An allotropic form of the element carbon consisting of layers of hexagonally arranged carbon atoms in a planar condensed ring system (graphene layers). The layers are stacked parallel to each other in a three-dimensional crystalline long-range order. There are two allotropic forms with different stacking arrangements, hexagonal and rhombohedral. The chemical bonds within the layers are covalent with sp(2) hybridization and with a C--C distance of 141.7 pm. The weak bonds between the layers are metallic with a strength comparable to van der Waals bonding only.
