Diamond and buckminsterfullerene C60\text{C}_{60}C60 are both allotropes of carbon.
Diamond has a sublimation point of approximately 3900 K3900\text{ K}3900 K.
Buckminsterfullerene sublimates at a much lower temperature of approximately 800 K800\text{ K}800 K.
Explain, in terms of structure and bonding, why the sublimation temperatures of diamond and buckminsterfullerene are so different.
