Abstract

We report the reactivity of a new Mn^I(cyclam) complex (cyclam: 1,4,8,11-tetraazacyclotetradecane) toward O₂ and H₂O as a model for the photoinhibited species of oxygen-evolving complex (OEC). The reactivity varies according to the number of CO ligands. A Mn^I dicarbonyl complex, [Mn^I(cyclam)(CO)₂]⁺ reacts with O₂, but not with H₂O, to form a bis(μ-oxo)Mn₂^III,IV complex, though a Mn^I tricarbonyl complex, [Mn^I(cyclam)(CO)₃]⁺ does not react with either O₂ or H₂O. Newly synthesized Mn^I(cyclam) dicarbonyl complex was characterized by ESI mass spectrometry, UVvis absorption spectroscopy, IR spectroscopy, and X-ray analysis.
