Lithium Cation Isolated Within Fullerene
Japanese scientists have for the first time isolated and determined the molecular and crystal structure of a cationic metallofullerene, Li@C60 (Nat. Chem., DOI: 10.1038/nchem.698). Although fullerenes with a metal or other small molecule inside the soccer-ball-like structure are nothing new, the lithium in this fullerene cage is both charged and, notably, off-center. Hiroshi Sawa of Nagoya University and Hiromi Tobita of Tohoku University note the ion state has not been seen before in . . .
