I'm no chemist, but I was under the impression that high pressure might allow for the creations of fullerenes even at these kinds of temperatures.
I didn't think they would float (but I can see how "hanging out" could be read that way).

Anyway, at so high pressure and density, I expect molecules with big voids to be crushed.
