Formation of Mn (hydro)peroxo complexes issued from addition of H2O2 to a [LMnII]2+ acetonitrile solution (L = pentadentate polypyridine ligand) is evidenced by low-temperature UV−visible spectroscopy, ESI-mass spectrometry, and parallel and perpendicular mode detection EPR spectroscopy. The influence of the medium (basicity, water content) on the formation of various species is investigated.
