Synthesis and characterization of a new iron(III) oxide cluster containing two different discrete [Fe3O] units: [Fe3O(O2CCHCHCH3)6(H2O)3][Fe3O(O2CCHCHH3)7(H2O)2] (HO2CCHCHCH3)4(OH)(H2O)

A new complex containing two different discrete trinuclear oxo-centered [Fe3O] units has been synthesized and characterized by single crystal X-ray diffraction analysis and Mössbauer spectra. The Mössbauer spectra of the complex are typical of high spin iron(III) complexes.
