Heating the spin-crossover (SCO) complex FeII(phen)2(NCS)2 (phen = 1,10-phenanthroline) under high vacuum results in the development of red movies that have been figured out as (SCN)2 by IR, Raman, and also UV-Vis spectroscopy. After annealing the red films to ∼140 °C under vacuum, purple (paramagnetic) films form and have actually been identified as Fe(phen)2(NCS)2 by octopus magnetometry, X-ray photoelectron, Raman and also IR spectroscopy. The Fe(phen)2(NCS)2 movies exhibit a SCO transition at ∼180 K through a broadened change temperature variety between the high-spin and also low-spin says (∼20 K) when compared to the bulk phase, i m sorry is ascribed to a vast distribution of molecule environments.
