Graphite Along with diamond, graphite is one of the standard forms of carbon. The atoms are arranged in sheets, in a hexagonal pattern like chicken wire. The sheets lie on top of each other. You can see the connection between graphite and nanotubes here.

Pentagons in Graphene Inserting a 5-sided pentagon into a sheet of 6-sided hexagons in graphene causes it to distort into a cone (12 pentagons cause it to wrap round into a ball - a C60 molecule). These images show the same structure from different angles.
Heptagons in Graphene A 7-sided heptagon on the other hand causes the sheet to buckle into a saddle shape. In combination, heptagons and pentagons can produce a range of graphitic structures with unusual curvature.

	Graphene Graphene has a similar structure to graphite but is a single isolated sheet of carbon.
	Graphene C62H20 A 'flake' of graphite with hydrogen used to terminate the dangling bonds.
	Graphene with adatom C63H20 A two-fold coordinated additional carbon atom on a graphene sheet (represents one of the stable structures of a carbon interstitial on graphite).
	Graphene with adatom pair C64H20 Two additional carbon atoms on a graphene sheet (represents an interstitial pair on the surface of graphite).
