One-pot reaction of AgSBu(t) 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 and are templated by an in situ generated S(2-) ion from the cleavage of the S-C bond of SBu(t) and CO3(2-) 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.
