Graphical Abstract

A stable bridge: A peroxo-bridged Fe–O2–Cu complex (see picture) was synthesized and isolated as crystals. The X-ray structure analysis revealed that the Fe–O2–Cu moiety has a μ-η2:η1 coordination mode; a peroxo ligand is bound to Fe in a side-on fashion with only one oxygen atom of the peroxide bound to Cu. The two metal ions (high-spin FeIII and CuII) were strongly coupled in an antiferromagnetic fashion, thus resulting in a total spin of S=2.
