Structural and electrochemical studies of Sm@D3h-C74 reveal a weak metal–cage interaction and a small band gap species

Abstract

A metallofullerene Sm@D3h-C74 that contains a divalent rare-earth metal has been studied structurally and electrochemically. The crystallographic analysis revealed that the endohedral Sm atom is more or less motional rather than being localized at a site where the pyracylene motif is nearby. This suggests a weaker metal–pyracylene interaction in Sm@D3h-C74 relative to that in MII@C74 (M = Group II metal), thus confirming the importance of the metal variety. The electrochemical studies showed a major difference between the redox properties of Sm@D3h-C74 and other Sm-fullerenes and indicated a small band gap for the title compound.
