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-η21 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.
