Carbon-carbon bond length is maximum in diamond because the diamond has a purely single bond.
The carbon atoms are held by strong covalent bonds and are arranged in a three-dimensional tetrahedral structure. Due to which diamond is hard. All the C-C bond are of the same length is 1.54 nm. In this rigid network, none of the carbon atoms can move. This accounts for the fact that diamonds are so hard and have such a high melting point.
While graphite, C70 (fullerene), and C60 (Buckminsterfullerene) single and partial double bonds.
