Isolation and Characterization of the DimetallofulltTcne Ce_2@C_(80)

摘要

The availability of pure metullofullerenes in milligram quantities has allowed a number of'metallofullerenes to be character-ixed by a variety of spectroscopic means. Although there have been some studies on Sc_m@C_(2n), the main research effort hasbeen directed towards metallofullcrenes of the type M@C_(82)H2 with a single encaged metal atom. The first soluble dimetallo-fullerene. La_2@C_(80), was reported soon after the method of synthesizing fullerenes on the macroscopic scale was developed.
