ABSTRACT: The present
paper deals with carbon in highly organized solids like graphene and its three-dimensional
derivatives: fullerenes, carbon nanotubes and capped carbon nanotubes. It proposes
an alternative to the typical bonding pattern exposed in literature. This novel
bonding pattern involves alternating positively and negatively charged carbon atoms
around hexagonal rings, then a few uncharged and partially bonded atoms close to
the pentagon rings. The article focuses on fullerenes inscribed into a regular icosahedron,
then addressing the most common fullerenes like C60. Carbon atoms are found to have
predominantly three single bonds and less often two separated single bonds. The same pattern explains equally well carbon
nanotubes and closed-tip nanotubes, of which C70 is a special case.
