Endohedral fullerenes are a fascinating class of compounds, that consist of a number of atoms trapped inside a fullerene cage structure. Among them, the Nitride Cluster Fullerenes (NCF) stand out for their stability and relatively high production yield. Sc3N@Ih-C80 is the most abundant species in this class. Its electronic structure and the relatively free rotation of the internal cluster make it a promising candidate for molecular electronics.

In the presented work, we use STM and AFM with a CO functionalized tip to characterize individual Sc3N@Ih-C80 molecules on Ag(111). This allows us to resolve their adsorption configuration and study the interaction of cage, cluster, and substrate in highest detail.

Studying Sc3N@Ih-C80 at the single molecule level provides direct access to its geometric and electronic characteristics, which are often hidden in bulk measurements.
