Spin doctoring : [Fe II H 3 L][Fe III L](NO 3 ) 2 , where H 3 L is a hexadentate tripod ligand bearing three imidazole groups, is formed in a one‐pot assembly reaction, and is shown to be a homochiral mixed‐valence spin‐crossover compound. The structure consists of a 2D assembled sheet that is held together by imidazole–imidazolate hydrogen bonds between [Fe II H 3 L] 2+ and [Fe III L] units (see picture). At least three electronic states can be accessed by temperature effects and photoirradiation.
