Abstract

Far-Infrared spectroscopical investigation of the spin-crossover in [Fe(II)(2,6-bis-(benzimidazol-2′-yl)-pyridine)2] (ClO4)2 exhibits a hysteresis in both CsI and polyethylene matrices within temperature cycles between 100 K and 520 K. The hysteresis broadening is dependent on the matrix and bigger in CsI. This can be explained due to polarity and hydrogen bonding. Two low spin vibrations, LSI at 437 cm-1 and LS2 at 424 cm-1, are observed. On heating from 100 K to 520 K: during LS1 decreases, the LS2 raises temporarily, until both LS1 and LS2 disappear; for the HS only one raising species was observed. This gives raise to assume two different sub-lattices.
