We report the efficient single-step synthesis of [2]catenane Rh-1, achieved through the self-assembly of 1,4-naphthalenediamine-derived bidentate ligands and binuclear half-sandwich rhodium(III) clips. Single-crystal X-ray diffraction confirms the interlocked structure of Rh-1. Density functional theory calculations reveal that π-π stacking and hydrogen bonding interactions play crucial roles in the formation and stabilization of Rh-1. In addition, the effects of ligand modification and metal ion substitution on the self-assembly process were also theoretically investigated from the perspective of thermodynamics. This work provides valuable insights for the rational design and synthesis of functional [2]catenanes and higher-order interlocked architectures.

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...
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 be...
