Abstract

Spin doctoring: [Fe^IIH₃L][Fe^IIIL] (NO₃)₂, where H₃L 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^IIH₃L]²⁺ and [Fe^IIIL] units (see picture). At least three electronic states can be accessed by temperature effects and photoirradiation.
