Abstract

The structure of La2@C80 is studied by La K-edge XAFS from 40 to 295 K. The distances between the La atom and the first nearest C atoms have been determined to be 2.42(1) Å at 40 K and 2.44(2) Å at 295 K, and those between the La atom and the second nearest C atoms to be 2.97(2) Å at 40 K and 2.98(3) Å at 295 K. The La-La distance has been determined to be 3.90(1) Å at 40 K and 3.88(2) Å at 295 K. The temperature dependence of the mean-square displacement of La-C is also studied to get an insight into the dynamical behavior of two La atoms in the C80 cage.
