Crystalline structure of diamond and graphite
WebDiamond and graphite have the same chemical composition (pure carbon) but different crystal structures. They are known as polymorphs of carbon. Diamond is formed under higher pressures than graphite (Figure 21), … WebThe crystal structure of diamond is an infinite three-dimensional array of carbon atoms, each of which forms a structure in which each of the bonds makes equal angles with its neighbours. If the ends of the bonds are connected, the structure is that of a tetrahedron, a three-sided pyramid of four faces (including the base).
