Significant charge transfer between a single-molecule magnet Mn12 and a Bi substrate

Single-molecule magnet Mn12 adsorbed onto a Bi substrate without linker molecules, where the Mn12 molecule is slightly tilted relative to the substrate such that the magnetic easy axis is several degrees away from the axis normal to the surface. Here charge transfer occurs from the Bi substrate (metallic surface states) to the Mn12 via mainly one of the outer Mn sites next closest to the substrate.
