| Description: |
The spin crossover salt [Fe(bpp)2](isonicNO)2 ·2.4H2O (1·2.4 H2O) (bpp = 2,6-bis(pyrazol-3-yl)pyridine; isonicNO = isonicotinate N-oxide anion) exhibits a very abrupt spin crossover at T1 /2 = 274.4 K. This triggers a supramolecular linkage (H- bond) isomerization that responds reversibly towards light irradiation or temperature change. Isotopic effects in the thermomagnetic behaviour reveal the importance of hydrogen bonds in defining the magnetic state. Further, the title compound can be reversibly dehydrated to afford 1, a material that also exhibits spin crossover coupled to H-bond isomerization, leading to strong kinetic effects in the thermomagnetic properties. |
