Abstract

We report the generation and spectroscopic characterization of a heterobimetallic [(TMC)Fe^III-O-Cr^III(OTf)₄] species (1) by bubbling O₂ into a mixture of Fe(TMC)(OTf)₂ and Cr(OTf)₂ in NCCH₃. Complex 1 also formed quantitatively by adding Cr(OTf)₂ to [Fe^IV(O)(TMC)(NCCH₃)]²⁺. The proposed O₂ activation mechanism involves the trapping of a Cr-O₂ adduct by Fe(TMC)(OTf)₂.
