The binding energies of O 2 and CO to iron(II) and manganese(II) porphyrin anions has been determined in the gas phase. Low‐pressure ion–molecule equilibria have been measured in a cryogenically cooled trap of an FT‐ICR mass spectrometer, and binding energies of (40.8±1.3) kJ mol −1 and (66.3±2.6) kJ mol −1 have been obtained for oxygen and carbon monoxide, respectively, with a heme‐analogue Fe II porphyrin complex.
