The endohedral metallofullerenes, such as Sc@C 82, Sc 2@ C 84, and Sc 3@ C 82, have been purified and isolated by using two-stage high-performance liquid chromatography (HPLC). The ESR spectrum of the isolated Sc 3@ C 82 exhibits a perfectly symmetric 22 hyperfined splittings with an inherent linewidth of 0.77 Gauss at 220 K, which is consistent with a unique structure that three scandium atoms are encaged triangularly within the C3v isomer of C 82. In addition, we report the direct imaging of the isolated discandium fullerene ( Sc 2@ C 84) on silicon clean surfaces in an ultrahigh-vacuum environment by utilizing scanning tunneling microscopy (STM). The STM images reveal spherical Sc 2@ C 84 fullerenes, spaced 11.7 Å apart, stacked in close-packed arrays.
