The electronic structure and the valency of the Sc ions in the endohedral dimetallofullerene Sc2@C84 with D2d symmetry are probed using high-energy spectroscopy. Comparison of the Sc 2p→3d x-ray-absorption spectrum with calculated ionic multiplet spectra shows that the Sc ions are trivalent. Detailed multiplet calculations including covalency indicate that the effective valency of the Sc(III) ions can be described by a formal charge transfer to the fullerene cage of 2.6±0.1. This illustrates that a purely ionic picture is not valid for the electronic structure of Sc2@C84 , and that a more complex picture including finite hybridization between the Sc and the fullerene cage has to be applied.
