Abstract

Structure of metal endohedral fullerenes is studied by XAFS and XANES. The Sc-Sc distance of 2.23(1) Å determined from Sc K-edge XAFS supports the formation of a triangular Sc₃ cluster in Sc₃@C₈₂ as is found by MEM analysis for the X-ray diffraction. Gd L_III-edge XAFS of Gd@C₈₂ shows that the first and the second neigboring Gd-C distances are 2.51(2) and 2.85(4) Å, respectively. The La-La distance of La₂@C₈₀ has been determined to be 3.90(1) Å at 40 K. This value does not change when increasing temperature [3.90(2) Å at 240 K]. The position and the valenece of the Eu atom in Eu@C₆₀ are also discussed based on Eu L_III-edge XAFS and XANES.
