The oxidization process of the Fe–Ni mixed Prussian blue analogue (Fe_0.2Ni_0.8)[Fe(CN)₆]_0.67·zH₂O was investigated by means of valence-differential spectroscopy. The spectroscopy revealed that the oxidization process selectively starts from the intermediate clusters. With a further increase in the oxidization level, all intermediate clusters are oxidized, and then Fe-rich clusters begin to be oxidized. On the basis of these results, we will discuss the redox process of the Ni–Fe cyano mixed crystal.
