Abstract

Cs K-edge extended X-ray absorption fine structure (EXAFS) spectra of Na2CsC60 are measured in order to determine the local structure around the Cs+ ion. The structural change accompanied by the order-disorder phase transition at 299 K is investigated in detail on the basis of the EXAFS spectra at 20, 295 and 317 K. It has been confirmed that Na2CsC60 takes a face-centered-cubic structure at 317 K, while it takes a simple-cubic structure at 20 and 295 K. It has also been found that the Cs+ ion at the octahedral site is not located out-of-center of the octahedral site but is located on the center.
