Spontaneous Reduction of High‐Spin Fe III Complexes Supported by Benzoic Hydrazide Derivative Ligands
Résumé
We report herein experimental evidence for the spontaneous reduction of new high‐spin iron(III) Fe III (L ( n ) ) 2 Cl, L complexes to new high‐spin iron(II) Fe II (HL ( n ) ) 2 Cl 2 mononuclear complexes. These processes were checked by EPR, cyclovoltammetric, and pseudo‐steady voltammetric studies. Crystal structures of three new complexes (one Fe III and two Fe II ) were obtained from RX single‐crystal diffraction.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
