Abstract
Prussian Blue analogs of the type Fe[MB(CN)6] (MB = Pd and Pt) crystallize in the face-centered cubic system: space group Fm3m-Oh 5, Z = 4. Magnetochemical and Mößbauer spectroscopic measurements have revealed that nitrogen-coordinated iron(II) ions and carbon-coordinated MB(IV) ions are in the high spin state and in the low spin state, respectively, in the temperature range 4.2 to 300 K. Upon the formation of Fe[MB(CN)6] from K2[MB(CN)6], the binding energies of N 1s, Pd 3d5/2 and Pt 4f7/2 increase while the C 1 s binding energy decreases. This tendency could be interpreted in terms of the inductive effect of iron(II) ions attached to the nitrogen end of cyanide ligands.Keywords
