Abstract
2D coordination polymer iron(II) spin crossover complexes containing 3,5-lutidine with host framework Fe(3,5-lutidine)2Ni(CN)4were synthesized. Their spin crossover properties were studied by temperature dependent 57Fe Mössbauer spectroscopy. Materials show gradual incomplete spin crossover with distinct thermochromism, while only 25 % of iron(II) ions are switched to the low spin state at 80 K, as determined by a detailed 57Fe Mössbauer study.
