Abstract

Abstract : 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 T 1/2 value and weak thermal hysteresis. Intermolecular structural details are related to the cooperativity features. Abstract : We describe the first example of a bis-tridentate heteroleptic iron(iii ) spin crossover (SCO) complex, [Fe(3-OMe-SalEen)(thsa)]. Compared to the parent homoleptic compounds, the spin crossover features in the heteroleptic species are enhanced with a gradual–abrupt spin transition at 344 K. Clear correlations between π–π interactions and the T 1/2 value have been revealed.
