In this study, the controlled synthesis of highly stable Ag56 clusters was achieved using 4-vinylbenzoic acid (p-VBA) and tert-butyl mercaptan as ligands by accurately tuning reaction parameters such as temperature and solvent. Additionally, intermediates Ag20, Ag31, Ag32, along with the dimers of A...
