Abstract

Changes in the nature of spin crossover caused by mechanical stressing exerted on the crystalline powders were studied for Fe^II(phen)₂(NCS)₂ (phen = 1,10-phenanthroline) and Fe^II[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.
