A stable bridge : A peroxo‐bridged Fe–O 2 –Cu complex (see picture) was synthesized and isolated as crystals. The X‐ray structure analysis revealed that the Fe–O 2 –Cu moiety has a μ‐η 2 :η 1 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 Fe III and Cu II ) were strongly coupled in an antiferromagnetic fashion, thus resulting in a total spin of S =2.
