Abstract:
A series of Sn(IV) chloride complexes with sulfur diimide (SDI, R-NSN-R) ligands are presented, including structural characterization of first-in-class complexes of bidentate diaryl-SDIs, [SnCl4{κ2-N,N'-S(NAr)2}] (Ar = 4-X-C6H4-), and an oxygen-coordinated sulfinylamine, [SnCl4{κ1-O-OSNPh}2]. As part of the comprehensive experimental and DFT computational investigation, 119Sn NMR analysis revealed a dynamic exchange equilibrium in acetonitrile between SDI ligands and solvent, providing insight into their complicated solution-state chemical and electrochemical behavior. Voltammetric experiments show that, despite this dynamic equilibrium, the SDI ligands appear to suppress typical Sn(IV) reduction pathways. While tentative due to the complex behavior, this suggests that SDIs are functioning as redox-active (RA) ligands. In conjunction with our previous systematic characterization of diaryl-SDIs, these findings highlight their potential as an easily derivatized and highly redox-tunable category of RA ligand and emphatically warrant further investigation.

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...
