Position determines properties : The oxidative properties of [Fe IV (O)(L)(X)] species (L=tetradentate N 4 ligand, X=monodentate ligand) depend on the position of the X ligand. The FeO unit is a poorer oxidant with an electron‐donating cis ligand but becomes a much better oxidant when this ligand is trans to the oxo group. This difference in reactivity reflects perturbations to the electronic structure of the highly covalent FeO moiety.
