“…This rearrangement seems to be rather moderate, owing to the low values of AOD/eDLs (-1 1% for 1 and 9% for 2), compared to those calculated from the Debye temperatures reported by Konig et al for a number of iron( I I ) spin-crossover complexes (1 4-30%). [29][30][31][32][33] A pronounced temperature dependence is observed for AEqHS (see Figure IO) whereas, as expected, AEqW is almost independent of temperature (see Table VI). Concerning these data, some points have to be emphasized.…”

“…23 46,47 In the former, a crystallographic phase transition between the HS and LS states at ambient pressure was demonstrated by powder diffraction. 48 In the case of [Fe(PM-Bia) 2 (NCS) 2 ], at ambient pressure there is no difference in crystallographic symmetry between HS and LS states; however, the possibility of a second (pressure-induced) phase of this material that does show such a crystallographic transition between spin states has been postulated to explain the increase in width of the hysteresis above 6 kbar. 46,47 An alternative explanation for the increase in hysteresis width is that there is an increase in the particle size distribution, for example, in the case of [Fe(bipy) 2 (NCS) 2 ], where the widening and flattening of the hysteresis is attributed to the mechanical grinding of the sample.…”

“…are parallel or antiparallel to each other. The stochastic model (I) was applied to the spectra of [Fe(mim),(salacen)]PF, because the isomer shift (6) values of the high-spin and low-spin isomers for the complex are observed in the region ca. 0.2-0.3 mm s-'; the difference is small and the quadrupole splitting (A) values decrease linearly on increasing temperature.…”
