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 LIII-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 LIII-edge XAFS and XANES.
