TRIPLY BRIDGED DIRUTHENIUM COMPLEXES WITH [RUIII2(MU-O)(MU-O2CCH3)2]2+ AND [RUIVRUIII(MU-O)(MU-O2CCH3)2]3+ CORES - SYNTHESIS, SPECTRA, AND ELECTROCHEMISTRY

Recently there has been a great deal of interest1, 2 in oxobridged dinuclear complexes of Fe(III) because of the discovery of diiron sites in an emerging class of oxobridged non-heme iron proteins and enzymes. This has stimulated discovery3 of a fast growing series of triply bridged iron(III) complexes. The present work originated from our search for [M2(μ-O)(μ-O2CR)2]2+ (M = Ru, Fe)269 cores using MeL as a facially capping ligand. Here we present the rich redox chemistry of the diruthenium complexes of the bridging type as shown in the diagram. © 1992, American Chemical Society. All rights reserved.
