What happens to the molecular orbital diagram when a metal-ligand complex is oxidized? Oxidation removes an electron, e.g. you go from d8 metal to d7 metal. As consequence the antibonding orbital has an unpaired electron making the complex less stable (weaker M-L bond, since less pi-backdonation), but how does it change the gap between the metal MO and LUMO of ligand, as well as the gap between the metal MO and HOMO of the ligand?
