A minor isomer of C84 fullerene, D6h-C84(24), captured as a trifluoromethylated derivative, C84(CF3)12

An isomer of C₈₄ fullerene, D_3d-C₈₄(24)(CF₃)₁₂, has been isolated by the HPLC method from the products of trifluoromethylation of C₈₄ fullerene mixture. Its molecular structure has been determined by a single crystal X-ray diffraction using synchrotron radiation. In the addition pattern, 12 CF₃ groups are arranged as a loop of edge-sharing para-C₆(CF₃)₂ hexagons. Isomer D_6h-C₈₄(24) has been identified in the form of a derivative for the first time.
