For the first time, two types of the metallofullerene Nd at C82 have been isolated and characterized. HPLC was used to isolate Nd at C82(I, II). The two isomers were characterized by mass spectrometry and UV-Vis-NIR absorption spectroscopy. Nd at C82(I) was found to be similar in structure to the main isomer of other lanthanofullerenes such as La at C82, as was previously reported. We assign Nd at C82(I) to have a C2v cage symmetry. Nd at C82(II) showed a markedly different UV-Vis-NIR absorption spectrum to Nd at C82(I). Its spectrum is in good agreement with that of the minor isomer of metallofullerenes such as Pr at C82. We therefore assign Nd at C82(II) to have a Cs cage symmetry. In contrast to other metallofullerenes, both isomers appear to be equally abundant.
