CHEMISTRY OF ENDOHEDRAL METALLOFULLERENE IONS : STRUCTURAL DETERMINATION OF THE La@C_(82) ISOMER

摘要

A stable diamagnetic monoanion of the La@C_(82) isomer was electrochemically prepared and isolated in order to disclose its cage symmetry. By measuring the ~(13)C NMR spectrum of the anion, it was determined for the first time that the isomer has C_s symmetry, as was also confirmed by density functional calculations.
