Abstract
Inelastic neutron scattering spectra in the range 20-200 cm(-1) are us ed to identify magnetic transitions in exchange-coupled oxo-centered t riiron(III) complexes. It is concluded that the triangular cluster in the compound [Fe3O(O2CCD3)(6)(C5D5N)(3)]NO3 is adequately described as isosceles, i.e, with two of the three J-values equal, but that the cl usters in K-5[Fe3O(SO4)(6)(D2O)(3)].6D(2)O and [Fe3O(O2CC(CD3)(3))(6)( DOCD3)(3)]Cl are scalene. The deviations of the clusters from equilate ral symmetry are discussed in terms of a magnetic Jahn-Teller effect.
