Changes in the nature of spin crossover caused by mechanical stressing exerted on the crystalline powders were studied for FeII(phen)2(NCS)2 (phen = 1,10-phenanthroline) and FeII[HB(pz)3]2 (pz = pyrazol-1-yl) by means of a multi-component fitting of the temperature dependence of magnetic susceptibility. The analysis revealed the development and broadening of the ligand field distribution as a consequence of mechanical stressing. This was confirmed by the broadening of Mössbauer and far-infrared spectra.
