The redox-active arylazothioformamide (ATF) ligand shows great potential as an alternative to many methods of precious-metal purification which require destructive methods or toxic chemicals. In researching syntheses of multiple variations of the ATF ligand and the complexes that they form, two types of complexes have been observed: a 1:1 system observed as 2:2, and a 2:1 system. Copper(I) halides like CuBr and CuI have formed 1:1 complexes with the ligand. Other salts such as Ag(I)PF6, (NBu4I)2(CuI2)4, and even solid gold have formed 2:1 complexes. These complexes and their formations have been studied through 1H NMR and UV-vis titrations, X-ray crystal structures, computational modeling of said crystal structures, and advanced equilibrium models to get a closer look at the binding mechanism and why the complexes behave so differently. This presentation will discuss how the computational and experimental data can be used to understand the binding mechanism of the ATF-complex formation.
