Abstract

Six new \(\mu _3 {\text{ - }} \)oxo trinuclear iron(III) complexes of the type [Fe3O(R–COO)6(H2O)3] \(\cdot \)X, where X=\({\text{NO}}_{\text{3}}^ - \) or Cl and R=C5, C7, C8, C9 were synthesized and investigated by Infra Red, Mössbauer Spectroscopy and magnetic measurements. The data pointed to a high spin state (S=5/2) for iron and for antiferromagnetic interactions. The asymmetrical shape of the Mössbauer doublet and its temperature dependence was treated using the Blume relaxation model. The relaxation process is influenced by both X and R components.
