Strong lowering of ionization energy of metallic clusters by organic ligands without changing shell filling

Metallic clusters with an excess electron beyond a closed shell have very low ionization energies, in analogy to alkali atoms. Here, the authors use select ligands to lower the ionization energy of metallic clusters without changing the number of valence electrons, introducing a route to alkali-like superatoms that is independent of the final shell occupancy.
