| Abstract: | Concentrated solutions of ferric nitrate as well as Fe(NO3)3·9H2O melt, have been investigated by an X-ray scattering technique. The data are consistent with the assumption, in both solutions and melt, of Fe(H2O)63+ complexes in octahedral configuration. The possible presence of the nitrato group in the inner Fe3+ coordination sphere is discussed. Polynuclear Fe3+ complexes are excluded by the experimental conditions of the investigated solutions. |
