arent the allotropes of carbon
diamond buckminsterfullerene(or whatever its called haha) and graphite?
When I was in school there were three allotropes of carbon; that is, diamond, graphite, and amorphous carbon (carbon black). Now there are a bunch AND i date myself. Here is a more modern site than I am modern. http://en.wikipedia.org/wiki/Allotropes_of_carbon
Here is another site but I think it lists the same items; I believe it is organized a little better than the last site I gave you.
