IR spectra are reported for the compounds [Fe3O(O2CC(CH3)(3))(6)(py)(3)][FeCl4] and [Fe3O(O2CC(CH3)(3))(6)(py)(3)]. Using isotopic substitution at the central oxygen atom, the assignments of the in-plane and out-of-plane vibrations of this atom are confirmed, and coupling is demonstrated between the in-plane modes nu(as)(Fe3O) and carboxylate deformation modes rho(r)(C-CO2).
