Abstract:
Macrocycle-based architectures are of importance in synthetic chemistry. Here, a novel parallelogram metallomacrocycle Fe2(LA)2 with reversible structural transformation was designed and synthesized. The template-free metalla[2]catenane [Fe2(LA)2]2 could be obtained by changing the concentration and has been monitored on the basis of NMR analysis. By redesigning the metallo-ligand, a catenane-like intersected parallelogram assembly with two shape-persistent supramolecular isomers was achieved. This work develops the field of terpyridine-based macrocycle system research and is valuable for obtaining other types of supramolecular isomerism.

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...

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
