single-crystal X-ray diffraction analysis. All six complexes adopt discrete structures, with 1,3,4,5 and 6 being dinuclear and 2 being tetranuclear, and Ag–Ag interactions were found to exist in complexes 1,2,3 and 6, as well as π–π stacking in 1–4. Furthermore, the Ag⋯Ag distances in 1–6 were compared. In the six complexes, the sulfur atoms of the ligands adopt quite different coordination modes: bridging
