Air-stable methyldisulfide-functionalized metal bis(terpyridine) complexes

Metal bis(terpyidine) complexes comprising directly connected methyldisulfide groups are synthetically accessible and air-stable in solution for ≥7 d, in stark contrast to their thiol analogues. These compounds exhibit a rich solution electrochemistry, and provide a robust foundation for future studies of this prominent class of molecules adsorbed on metal surfaces.
