Manganese adamantane structure

The results of the XAS and EPR data, combined with knowledge from model complexes, (discussed later) allow for the formulation of structural models of the OEC. Many manganese compounds have been proposed as structural models for the OEC, ranging from butterfly arrangements to adamantanes to cubanes (26, 27,29-34, 50). Most of those proposals, however, are inconsistent with the known structural data for the OEC. Currently the most widely favored model is the dimer of dimers model (Scheme 11), first suggested by Klein,...
