title: Popular C82 fullerene cage encapsulating a divalent metal ion Sm(2+): structure and electrochemistry.
abstract: Two Sm@C82 isomers have been well characterized for the first time by means of (13)C NMR spectroscopy, and their structures were unambiguously determined as Sm@C2v(9)-C82 and Sm@C3v(7)-C82, respectively. A combined study of single crystal X-ray diffraction and theoretical calculations suggest that in Sm@C2v(9)-C82 the preferred Sm(2+) ion position shall be located in a region slightly off the C2 axis of C2v(9)-C82. Moreover, the electrochemical surveys on these Sm@C82 isomers reveal that their redox activities are mainly determined by the properties of their carbon cages.
