Charge transfer in mixed-valence solids. Part VIII. Contribution of valence delocalisation to the ferromagnetism of Prussian Blue

Abstract

The contribution of mixed-valence electron delocalisation to the ferromagnetic exchange between the iron(III) ions in Prussian Blue {FeIII4[eII(CN)6]3·14H2O} has been estimated theoretically. Agreement between the calculated and observed values of the Curie temperature is quite good.
