Four CF₃ derivatives of C₇₈, C₇₈(2)(CF₃)_10/12 and C₇₈(3)(CF₃)_12/14 , have been isolated via HPLC from the products of high-temperature trifluoromethylation of a C₇₆–C₉₆ fullerene mixture or a C₇₈ fraction. Their molecular structures were determined by single crystal X-ray crystallography using synchrotron radiation. The addition patterns of the new compounds are compared with each other and with the previously known C₇₈(2)(CF₃)₁₀ and C₇₈(3)(CF₃)₁₂.

Keywords: higher fullerenes, C₇₈, trifluoromethylation, HPLC, structure elucidation.
