The oxidation state of the metal also contributes to the size of Δ between the high and low energy levels. As the oxidation state increases for a given metal, the magnitude of Δ increases. A V complex will have a larger Δ than a V complex for a given set of ligands, as the difference in charge density allows the ligands to be closer to a V ion than to a V ion. The smaller distance between the ligand and the metal ion results in a larger Δ, because the ligand and metal electrons are closer together and therefore repel more.
