Abstract
| - The hydroxide-bridged Cr(III)−Mn(II) complex [(Me3tacn)Cr(μ-OH)(μ-CH3CO2)2Mn(MeDPA)]2+ (Me3tacn = tri-N,N‘,N‘ ‘-methyltriazacyclononane, MeDPA = N-methyl-N-bis(2-pyridylmethylamine) is oxidized by the 2,4,6-triphenylphenoxide radical to give the oxo-bridged Cr(III)−Mn(III) complex [(Me3tacn)Cr(μ-O)(μ-CH3CO2)2Mn(MeDPA)]2+. This reaction is a potential model for H-atom abstraction steps in mechanistic proposals for water oxidation in photosynthesis.
