The iron(iii) bis-tridentate complex [Fe(3-OMe-SalEen)(thsa)] is the first heteroleptic iron(iii) spin crossover complex and displays a very high T1/2 value and weak thermal hysteresis. Intermolecular structural details are related to the cooperativity features.

Hysteresis Loop Width

Wide thermal hysteresis loops for iron(ii) spin crossover complexes are associated with high activation barriers: the higher the activation barrier, the wider the hysteresis loop for a series of related spin crossover systems.
