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.
