摘要：

The structure of La-2@C-80 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) Angstrom at 40 K and 2.44(2) Angstrom at 295 K, and those between the La atom and the second nearest C atoms to be 2.97(2) Angstrom at 40 K and 2.98(3) Angstrom at 295 K. The La-La distance has been determined to be 3.90(1) Angstrom at 40 K and 3.88(2) Angstrom 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 C-80 cage. (C) 2001 Elsevier Science B.V.
