The manipulation of the molecular spin state byatom doping is an attractive strategy to confer desirable magneticproperties to molecules. Here, we present the formation of novelmagnetic metallocenes by following this approach. In particular,two different on-surface procedures to build isolated and layer-integrated Co-ferrocene (CoFc) molecules on a metallic substratevia atomic manipulation and atom deposition are shown. Thestructure as well as the electronic properties of the so-formedmolecule are investigated combining scanning tunneling micros-copy and spectroscopy with density functional theory calculations.It is found that unlike single ferrocene a CoFc molecule possesses amagnetic moment as revealed by the Kondo effect. These results correspond to the first controlled procedure toward thedevelopment of tailored metallocene-based nanowires with a desired chemical composition, which are predicted to be promisingmaterials for molecular spintronics.
