  "abstract": "The interest in spin crossover for solid-state cooling is growing. We investigate the spin crossover transitions of [Fe(pyridine)2Fe(CN)5NO] and [Fe(pyrazine)Fe(CN)5NO] by single-crystal X-ray diffraction, high-pressure X-ray diffraction, magnetometry, and high-pressure calorimetry. The dehydrated form of the latter compound shows a reversible cooling effect (∆Tad,rev) of ∼15K at 1.2 kbar. This is high in the context of other reported spin-crossover barocalorics, and competitive within the field at large. The excellent performance results from a large barocaloric coefficient (dT1/2/dp = 35K kbar−1). In addition, the one-pot synthesis is simple and free from toxic solvents.",
