The linear FeOFe bridge in μ‐oxo tetraphenylporphyrin iron(III) dimer can be protonated without structural rehybridization at the O atom (the structure of the μ‐hydroxo‐bridged complex is depicted on the right). Antiferromagnetic coupling between the iron centers is greatly attenuated, and proton self‐exchange is slow.
