A highlyoxidizedcobaltporphyrindimer is reported. Each cobalt(II) ion and porphyrin ring underwent 1e oxidation with iodine as the oxidant to give a 4e‐oxidizedcobalt(III) porphyrin π‐cation radical dimer. The bridging ethylene group allows for substantial conjugation of the porphyrin macrocycles, thus leading to a strong antiferromagnetic coupling between the π‐cation radicals and to stabilization
