Pressure-Tuning of Magnetism and Linkage Isomerism in Iron(II) Hexacyanochromate, "Journal of the American Chemical Society (JACS)", vol. 127, 4580-45810002-7863http://hdl.handle.net/10347/32224A pressure-induced linkage isomerization of the cyanide anion has been observed in single crystals of a chromium(III)−iron(II) Prussian blue analogue of formula K0.4Fe4[Cr(CN)6]2.8□1.2·16H2O (1). Upon application of pressure in the 0−1200 MPa range, the cyanide ligand rotates and becomes C-bonded to the iron(II) cations, leading to a stabilization of their diamagnetic low-spin states. The result is a decrease of magnetization and magnetic ordering temperatures from TC = 19 K at ambient pressure to 13 K at 1200 MPa. The initial magnetic properties can be restored on pressure release. The reversible movement of cyanide in the solid state can be exploited as a switch of the magnetic interaction at the molecular level.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Cyanide anionDiamagneticMagnetic interaction2303 Química inorgánicajournal article10.1021/ja043166z1520-5126open access
