Charging hemifullerene C 30 H 12 with potassium metal gives the hexaanion C 30 H 12 6− ( 1 6− ). The NMR data, which indicate high symmetry, high charge density, and pyramidalization of the C‐4 positions, as well as DFT calculations, are consistent with a tetramer [ 1 6− ] 4 /24 K + , in which six K + ions bridge four hexaanions (see picture; red K + , yellow H, blue C; the remaining 18 solvent‐separated K + ions are not shown).
