By studying three types of POV6 with the very common potassium, ammonium, hydrogen, lithium, and magnesium counterions, we observed a significant dependence of the charge distribution of these complexes on the cation type. Without loss of generality, we consider only the systems with a type I ligand, as they are computationally more affordable and behave like the other ligands of types II and III (Fig. ). All types of cations employed in this work stabilize the charged POV6 core. With the monovalent cations, the POV6 can accommodate at least four additional electrons. Balanced by protons serving as counterions, stable uptake of up to nine electrons is observed (Fig. ). The structural integrity of the POV6 is maintained for all states reported herein (Fig. , Fig. , Table ). In contrast, the divalent magnesium counterions do not achieve double ionization: If 4 Mg atoms are added to the system, only 4 of them are transferred to the POV6 core, and the structure of the latter is slightly changed (Fig. ).
