摘要：

(Chemical Equation Presented) A ferryl cation in water: Iron(II) coordinated by the pentadentate ligand L reacts with H2O2 to form a low-spin FeIV=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. © 2006 Wiley-VCH Verlag GmbH & Co.
