Discernible apical coordination in μ3-oxo-bridged mixed metal trinuclear carboxylate [Fe2MnO(CHCl2COO)6(THF)2H2O]

Novel μ3-oxo-bridged heterotrinuclear iron(III)-manganese(II) carboxylate of the composition [Fe2MnO(CHCl2COO)6(THF)2H2O] has been synthesized and characterized by X-ray crystallography, IR and TG. The positional parameters of the various metal ions within trinuclear [Fe2MnO]6+ core were determined unambiguously due to their different coordination environment and hydrogen bonds forming between two H2O molecules coordinated to Mn ions in different clusters.
