The structural influences of the supporting carboxylate ligand on biologically relevant Fe/O 2 chemistry are emphasized by the unusual Raman and Mössbauer spectroscopic properties of the intermediate derived from 1 relative to those of known (peroxo)diferric species. These (peroxo)diferric intermediates were generated from paddlewheel complexes (L=py, MeIm, and thf) of the new carboxylate ArCO 2 − ligand on reaction with O 2 . MeIm=1‐methylimidazole, py=pyridine.
