Here we report the first {sup 13}C-NMR results on the metallofullerene, Sc{sub 2}@C{sub 84}, which determines an isomer cage structure for the metallofullerene. The Sc{sub 2}@C{sub 84} fullerene was separated and isolated from the various hollow fullerenes (C{sub 60}-C{sub 110}) and other scandium metallofullerenes by the multistage high-performance liquid chromatography (HPLC) method by using two complementary types of HPLC columns. The purity of Sc{sub 2}@C{sub 84} relative to other fullerenes was more than 99.9%. {sup 13}C-NMR measurements were made using a 600 MHz NMR (JEOL JNM-A600) at room temperature in CS{sub 2} solvent. 30 refs., 3 figs.
