The structural determination of endohedral metallofullerene Gd@C(82) by XANES

Although the Gd ion in Gd@C(82) has been shown to lie above the C-C bond on the C(2) axis as an anomalous structure from the MEM/Rietveld analysis, the present XANES study reveals that it lies above the hexagon on the C(2) axis as a normal structure, and Gd oscillates around its equilibrium position with an amplitude increasing with temperature increase.
