Negative ion/description chemical ionization mass spectrometry was used in this paper to characterize La{sub x}@C{sub n} and Y{sub x}@C{sub n} fullerenes in soot generated from metal compound-impregnated graphite rods. La@C{sub 82} and La@C{sub 80} are extracted by pyridine from the soot, but La@C{sub 60} and La@C{sub 70} are not. There are greater abundances of metallofullerenes with the lower ionization potential metal atom in the pyridine extracts. These observations indicate that metallofullerenes exist as ionic complexes with fullerenes (La{sub x}@C{sub n}){sup +}C{sub n}{sup -}. 16 refs., 4 figs.
