    Two isomers of Dy@C82 were separated by high performance liquid chromatography (HPLC), and their UV-VIS absorption spectra were measured to characterize these isomers. The crystalline powder of Dy@C82 was obtained by removing the solvent (toluene) at 250°C under vacuum. The X-ray diffraction pattern can be indexed with fcc crystal lattice, as that in La@C82. The lattice constant a at 298 K, 15.86(1) Å, is close to that of La@C82, 15.78 Å. The distances between Dy and the first and second nearest C atoms are determined to be 2.52(2) and 2.86(2) Å, respectively, on the basis of Dy LIII-edge EXAFS. The XANES shows that the valence of the Dy atom in Dy@C82 is +3.
