Abstract

A high-temperature, high-pressure extraction technique with toluene and pyridine were employed for the extraction of metallofullerenes Gd@C_2n. A series of Gd@C_2n for 2n from 70 to 96 were effectively extracted by toluene. Gd@C₇₄ was shown to be a new stable soluble metallofullerene species. Pyridine was found to be more useful for the extraction of Gd@C₈₂ and Gd₂@C₈₀ from empty fullerenes and other metallofullerene species.
