Koltover, Ya. Estrin, V. Bubnov, E. Laukhina] The EPR spectra of endohedral metallofullerenes (EMF), La-EMF and Y-EMF, which were free of admixtures of C60 and of other empty fullerenes, were examined. Endohedral metallofullerenes were prepared by extraction of fullerene-containing soots with DMF. New signals withg factors close to those of fullerene radical anions were observed in the EPR spectra of solutions of EMF in DMF and DMSO. At −20 °C, these signals are observed as a doublet (ΔH pp ≈0.04 mT) and singlet (ΔH pp ≈0.01 mT) in solutions of La-EMF and Y-EMF, respectively. These EPR signals belong to solvated La@C82 and Y@C82 molecules and are characterized by small hyperfine interaction constantsa M due to a substantial decrease in the spin density of the unpaired electron at the metal atom.
