Sm@C(2v)(3)-C(80) has been separated from the carbon soot produced by electrical arc vaporization of graphite rods doped with Sm(2)O(3) and purified. Its structure has been determined by single crystal X-ray diffraction using cocrystals obtained from either Ni(II)(octaethylporphyrin) (Ni(II)(OEP)) to form
