Spin crossover in the Prussian blue analogue FePt(CN)(6 )induced by pressure or X-ray irradiation

• The spin state of the Prussian blue analogue (FePtIV)-Pt-II (CN)(6) is investigated in response to temperature, pressure, and X-ray irradiation. White cooling to 10 K maintains the high-spin state of Fe-II, compression at ambient temperature induces a first-order spin-crossover (SCO) transition with a small hysteresis loop (p up arrow = 0.8 GPa, p down arrow= 0.6 GPa). In addition, the high-spin to low-spin transition can be initiated at lower pressure through increased X-ray irradiation. Our study highlights a cooperative SCO with moderate pressure in a porous Prussian blue analogue.
