Trifluoromethyl and chloro derivatives of a higher fullerene D2-C80(2): C80(CF3)12 and C80Cl28.

Two derivatives of the low-abundant D2-C80 (isomer 2), C80(CF3)12 and C80Cl28, have been synthesized, isolated, and structurally characterized by single-crystal X-ray crystallography. Notably, the addition pattern of C80(CF3)12 is the same as that of the known C80Cl12. The molecule of C80Cl28 contains very short (1.33 Å) and very long (up to 1.62 Å) C-C bonds in its carbon cage.
