Abstract
Solvent-, acidity-, and redox-responsive thione(thiol)–disulfide interconversion were achieved by a dinuclear copper(ii) complex bearing a bis(thiosemicarbazone) (bTSC) ligand. The role of copper(ii) ion coordination was rationalized by parallel comparison with a bare bTSC ligand and zinc(ii) bTSC complexes under identical reaction conditions.

We explored bis(thiosemicarbazone) as a chelating ligand of copper(II) and zinc(II) ions to probe the thione–disul de interconversion mechanism
