Abstract

The first tetrameric high valent manganese complex consisting of a MnIV4(μ-O)5 bridged core, [Mn4(μ-O)5(dmb)4(dmbO)2](ClO4)4, was isolated via dimanganese (III,IV) and (IV,IV) intermediates in presence of the oxidant tert-butyl hydroperoxide and was characterized by X-ray crystallography, electrochemistry, infrared, UV-visible, 1H NMR, and mass spectroscopy; the structure found differs greatly from a proposal for the putative Mn4O5 aggregate found in Photosystem II.
