Crystal structure and bonding of ordered c60
WebIf the ends of the bonds are connected, the structure is that of a tetrahedron, a three-sided pyramid of four faces (including the base). Every carbon atom is covalently bonded at the four corners of the tetrahedron to four other carbon atoms. The distance between carbon atoms along the bond is 1.54 × 10 −8 cm, and this is called the single ...
