Two iron/cobalt mixed-valence clusters were synthesized using multidentate polypyridyl ligands (see picture: FeII orange, FeIII yellow, CoII blue, O red). A heptanuclear helix and a [3×3] grid complex form depending on the metal ion stoichiometry. ESI-MS measurements suggest that the helical cluster is an intermediate to the grid complex.
