The structure of a 1,2-phenylene linked dicobalt tetraarylporphyrin dimer was determined by X-ray crystallography and its dioxygen adduct was characterized by absorption and ESR spectroscopies. Since the porphyrin dimer has a long metal-metal distance and a rigid framework against inward bending, the cobalt centers were not bridged by the coordinated dioxygen.
