Abstract

We report three self-assembled iron complexes that comprised an anti-parallel open form (o-L _anti ), a parallel open form (o-L _syn ), and a closed form (c-L) of diarylethene conformers. Under kinetic control, Fe ^II ₂ (o-L _anti ) ₃ was isolated, which exhibited a dinuclear structure with diamagnetic properties. Under light-irradiation control, Fe ^II ₂ (c-L) ₃ was prepared and exhibited paramagnetism and spin-crossover behaviour. Under thermodynamic control and in the presence of indispensable [Fe ^III (Tp*)(CN) ₃ ] ⁻ , Fe ^II ₂ (o-L _anti ) ₃ and Fe ^II ₂ (c-L) ₃ transformed into tetranuclear Fe ^III ₂ Fe ^II ₂ (o-L _syn ) ₂ , which exhibited complete spin-crossover behaviour at T _1/2 =353 K.
