Abstract

Bioinspired organometallic chemistry: An oxoiron(IV) unit has been trapped within a macrocyclic tetracarbene ligand, merging a key bioinorganic intermediate with a popular organometallic scaffold (see picture). The stability of the new complex has allowed its characterization by a variety of methods, which show a strong σ-donating tetracarbene coordination leading to an S=1 ground state and unusual properties of the oxoiron(IV) species.
