摘要：

Using a two-step liquid chromatographic method, the metallofullerene LaC82 has been isolated for the first time from the carbon soot. The isolated LaC82 was well identified as a stable molecule classified to a novel family of fullerene cage molecules. Comparison of the IR absorption spectra between LaC82 and C82 empty fullerene suggests an endohedral form for LaC82 with the same cage structure (C2 SYMMetry) previously proposed for C82. The presence of electronic absorption in the near-infrared region strongly supports the formation of an open-shell electronic structure for LaC82.
