Abstract:
We report three self-assembled iron complexes that comprised an anti-parallel open form (o-Lanti ), a parallel open form (o-Lsyn ), and a closed form (c-L) of diarylethene conformers. Under kinetic control, FeII 2 (o-Lanti )3 was isolated, which exhibited a dinuclear structure with diamagnetic properties. Under light-irradiation control, FeII 2 (c-L)3 was prepared and exhibited paramagnetism and spin-crossover behaviour. Under thermodynamic control and in the presence of indispensable [FeIII (Tp*)(CN)3 ]- , FeII 2 (o-Lanti )3 and FeII 2 (c-L)3 transformed into tetranuclear FeIII 2 FeII 2 (o-Lsyn )2 , which exhibited complete spin-crossover behaviour at T1/2 =353 K.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
