A ferryl cation in water: Iron(II) coordinated by the pentadentate ligand L reacts with H 2 O 2 to form a low‐spin Fe IV O complex with S =1 ( 2 in scheme) under conditions similar to those of the classical Fenton reaction. Complex 2 differs from a recently obtained high‐spin aquated oxoiron(IV) species and demonstrates the role of the supporting polydentate ligand in controlling spin state and product formation.
