A FeII-based 1D open framework that exhibits room-temperature spin- crossover (SCO) is reported. This material shows a reversible structural, magnetic, and chromatic response to a sorption/desorption process, allowing the tuning of the spin-transition properties by choosing the appropriate solvent. This feature represents the first example of a bifunctional material in which host–guest properties directly influence the SCO properties.
