Times Cited Count:18 Percentile:48.60(Chemistry, Physical)We report first STM observation of the Li
ion endohedral C
, which is of a new class of endohedral fullerenes, prepared by means of evaporation of high-purity Li
@C
[PF
] salt in ultra-high vacuum. Prior to the STM measurements, the electronic structure of Li
@C
in the Li
@C
[PF
] salt was also precisely determined. In the salt, it is shown that Li and PF
have nearly single positive and negative charge, respectively, and the C
cage is nearly neutral, suggesting that Li
@C
in the salt retains its original electronic state.
