Coinage Metal Complexes with Di?tertiary?butyl Sulfide as Precursors with Ultra?Low Decomposition Temperature

We report here the synthesis of [Cu2(TFA)4(tBu2S)2] (1), [Ag4(TFA)4(tBu2S)4] (2) and [AuCl(tBu2S)] (3) (TFA=trifluoroacetate), which decompose in solution medium at ultra-low temperature (e. g., boiling toluene) to afford phase-pure highly crystalline Cu9S5, Ag2S metallic Au nanoparticles, respectively. The low decomposition these precursors is attributed facile mechanism di-tertiary-butyl sulfide ligand. These results are a significant step direction establishing general low-temperature strategy spanning range systems including thermodynamically metastable materials incorporate them technologies that sensitive harsh conditions.
