Abstract

Rb K-edge EXAFS has been studied for K2RbC60 at 21 and 39 K and for KRb2C60 at 10 and 27 K. It is shown that the Rb+ ions in K2RbC60 occupy the center of the octahedral site, contrary to a previous report based on Rb K-edge EXAFS at room temperature that the Rb+ ions are off-centered. It is also found that the Rb+ ions in KRb2C60 occupy the octahedral and two tetrahedral sites.
