Popular C-82 Fullerene Cage Encapsulating a Divalent Metal Ion Sm2+: Structure and Electrochemistry

Two Sm@C-82 isomers have been Well Characterized for the first time by means of C-13 NMR Spectroscopy, and their structures were unambiguously determined as Sm@C-2v(9)-C-82 and Sm@C-3v(7)-C-82, respectively. A combined study of single crystal X-ray diffraction and theoretical calculations Suggest that in Sm@C-2v(9)-C-82 the preferred Sm2+ ion position shall be located in a region slightly off the C-2 axis of C-2v(9)-C-82. Moreover, the electrochemical surveys on these Sm@C-82 isomers reveal that their redox activities are mainly determined by the properties of their carbon cages.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000350391600007&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Chemistry, Inorganic & NuclearSCI(E)PubMed2ARTICLEzjshi@pku.edu.cn; fenglai@suda.edu.cn52103-21085
