A highly specific and catalytic oxidation of water occurs when using a dinuclear Mn complex of a mononegative carboxylate‐containing pentadentate ligand (see scheme). Isotope‐labeling experiments coupled with membrane inlet mass spectrometry show that one oxygen atom in the evolved O 2 molecule is derived from water and the other from the oxidant.
