Synthesis and X-ray structure of C2-C84(22)(CF3)6

C₂-C₈₄(22)(CF₃)₆ was isolated by HPLC from the products of trifluoromethylation of fullerene C₈₄. Its molecular structure elucidated by single crystal X-ray diffraction has an addition pattern with a six-membered chain of para additions of CF₃ groups. C₂-C₈₄(22)(CF₃)₆ is the most stable isomer on a pathway to the known C₂ and D₂ isomers of C₈₄(22)(CF₃)₁₂; the molecular structure of the latter was refined with a better accuracy.
