A Diferric Peroxo Complex with an Unprecedented Spin Configuration: AnS=2 System Arising from anS=5/2, 1/2 Pair

Abstract

In a spin: Transient peroxo iron complexes have been characterized by the means of Mössbauer and HF-EPR spectroscopies. Complex 1 has an unexpected S=2 ground state resulting from the coupling between the S=5/2 and S=1/2 iron(III) ions.
