One-pot reaction of AgSBut and AgOAc in the methanol–ethanol–DMF solvent system under room temperature gave a ball-shaped Ag56 cluster and a disc-like Ag20 cluster. The formations of clusters 1 and 2 are templated by an in situ generated S2− ion from the cleavage of the S–C bond of SBut and CO32− ion from the fixation of atmospheric carbon dioxide, respectively. Interestingly, cluster 1 only emits bright-red light in the solid state at 77 K and is not emissive at room temperature.
