Abstract

The Sc@C₇₄and Sc₂@C₇₄metallofullerenes (MF), adsorbed on the Si(100)2 x 1 clean surface were successfully studied for the first time by the STM. The STM showed that the MF molecules were imaged to be spherical, quite similar to those of C₆₀, C₇₀, and C₈₄, suggesting that Sc atoms were trapped inside the fullerene cage and that the charge is at least partially delocalized over the sphere of the cage. Statistical analysis of both the diameter and height of MF, compared with those of C₆₀, showed that the diameter of the Sc@C₇₄and Sc₂@C₇₄cages was 9.5 Å in average, larger than that of the pristine fuller enes.
