Fullerene structures possess many symmetries. This is because the molecules are round. More informations such as bond lengths, radii of the molecules can be view here

Reactivities of fullerenes

The most exciting characteristic of the buckyball is that it is hollow on the inside, and some elements in the periodic table will fit inside. This creates the main reactivity fo fullerenes.

Fullerenes reacts with many elements. This includes metallic element and non-metallic elements. Example are the reaction of fullerenes with Noble Gas and the reaction of fullerenes with metal. Fullerenes also react with metals to form Metallocarbohedrenes.
