WebFor both forms of graphite the in-plane C-C distance is 142 pm, i.e., intermediate between Csp 3 -Csp 3 and Csp 2 =Csp 2 bond lengths, 153 and 132 pm respectively, Table 1. Consideration of the resonance structures between carbon atoms in the plane show that each C-C bond in the carbon layer plane has about one third double bond character. WebGraphite: 120° and Diamond: 109°; C60 fullerene: bond angles between 109-120°; Allow Graphite: sp 2 and Diamond: sp 3 . Allow C60 fullerene: sp 2 and sp 3 . Number of atoms each carbon is bonded to Graphite and C60 fullerene: each C atom attached to 3 others; Diamond: each C atom attached to 4 atoms / tetrahedral arrangement of C (atoms);
