ABSTRACT: Carbon forms a variety of compounds with single, double, triple and the intermediate resonance
bonds with atoms of its own or other kinds. This paper is concerned with graphite, a very useful
material, which is a stack of electrically conducting graphene layers held together by weak van der
Waals (vdW) bonds. It crystallizes in hexagonal and rhombohedral forms, in which the hexagon
inter-planar bond distance is 0.34 nm. Here a new and simple approach accounts for this bond
length and shows the coulombic nature of the vdW bond.
