摘要

The first example of a microcrystalline powder of a synthetic low-spin (LS) mononuclear Fe-III(OOH) intermediate has been obtained by the precipitation of the [Fe-III(L-5(2))(OOH)](2+) complex at low temperature. The high purity of this thermally unstable powder is revealed by magnetic susceptibility measurements. EPR studies on this complex, in the solid state and also in frozen solution, are reported and reveal the coexistence of two related Fe-III(OOH) species in both states. We also present a theoretical analysis of the g tensor for LS Fe-III complexes, based on new perturbation equations. These simple equations provide distortion-energy parameters that are in good agreement with those obtained by a full-diagonalization calculation.
