Abstract

In this work, we observed a spin-crossover phenomenon in a cesium iron hexacyanochromate, which is a Prussian blue analogue. This compound showed a thermal phase transition with transition temperatures of 211 K (T_1/2↓) and 238 K (T_1/2↑) due to a spin-crossover on FeII sites. This spin-crossover phase transition is accompanied by a lattice contraction of 0.38 Å, but maintains a face-centered cubic structure (F 3m). This is the first observation of FeII spin-crossover in a series of Prussian blue analogues.
