We report here the synthesis of [Cu 2 (TFA) 4 ( t Bu 2 S) 2 ] ( 1 ), [Ag 4 (TFA) 4 ( t Bu 2 S) 4 ] ( 2 ) and [AuCl( t Bu 2 S)] ( 3 ) (TFA=trifluoroacetate), which decompose in solution medium at ultra‐low temperature (e. g., in boiling toluene) to afford phase‐pure and highly crystalline Cu 9 S 5 , Ag 2 S and metallic Au nanoparticles, respectively. The low decomposition temperature of these precursors is attributed to the facile decomposition mechanism in the di‐tertiary‐butyl sulfide ligand. These results are a significant step in the direction of establishing a general low‐temperature strategy spanning a range of systems including thermodynamically metastable materials and incorporate them in technologies that are sensitive to the harsh conditions.
