Abstract:
Prussian blue (PB) is a well-known archetype of mixed valency systems. In magnetic PB analogues {C x A y [B(CN) 6 ] z }. n H 2 O (C alkali cation, A and B transition metal ions) and other metallic cyanometallates {C x (AL) y [B(CN) 8 ] z }. n H 2 O (L ligand), the presence of two valency states in the solid (either A–B, or A–A′ or B–B′) is crucial to get original magnetic properties: tunable high Curie temperature magnets; photomagnetic magnets; or photomagnetic high-spin molecules. We focus on a few mixed valency pairs: V(II)/V(III)/V(IV); Cr(II)/Cr(III); Fe(II)–Fe(III); Co(II)–Co(III); Cu(I)–Cu(II); and Mo(IV)/Mo(V), and discuss: (i) the control of the degree of mixed valency during the synthesis, (ii) the importance of mixed valency on the local and long-range structure and on the local and macroscopic magnetization, and (iii) the crucial role of the cyanide ligand to get these original systems and properties.
