Abstract

For the first time, two types of the metallofullerene Nd@C₈₂ have been isolated and characterized. HPLC was used to isolate Nd@C ₈₂(I, II). The two isomers were characterized by mass spectrometry and UV-Vis-NIR absorption spectroscopy. Nd@C₈₂(I) was found to be similar in structure to the main isomer of other lanthanofullerenes such as La@C₈₂, as was previously reported. We assign Nd@C₈₂(I) to have a C_2v cage symmetry. Nd@C₈₂(II) showed a markedly different UV-Vis-NIR absorption spectrum to Nd@C₈₂(I). Its spectrum is in good agreement with that of the minor isomer of metallofullerenes such as Pr@C₈₂. We therefore assign Nd@C₈₂(II) to have a C _s cage symmetry. In contrast to other metallofullerenes, both isomers appear to be equally abundant.
