In the past 5 years studies on the properties of cobalt(II) oxygen carriers1 have afforded an excellent opportunity to attack some of the central questions regarding biological oxygen carriers. More recently, it has been found that synthetic iron(II) systems can be reversibly oxygenated,2 offering further opportunities of characterizing transition metal-dioxygen interactions. We now have investigated the interaction of dioxygen with meso-tetraphenylporphyrin-(pyridine)manganese(II), Mn(TPP)(py), and report the first observations of reversible adduct formation between a manganese porphyrin and dioxygen.
