| Sumario: | The synthesis of heterobimetallic cluster with the Al--S--M (M = Cu and Ag) structural unit has been realized for the first time by the reaction of aluminum-dithiol LAl(SH) (L = HC[C(Me)N(Ar)], Ar = 2,6-iPrCH) with (MesCu) and (MesAg) (Mes = 2,4,6-MeCH), respectively. The isolated clusters exhibit core structures of AlCuS and AlAgS, respectively. During the formation of the [LAl(SAg)], a side product of LAlS is formed. However, the reaction of LAl(SH) with excess of sulfur and (MesAg) resulted in the formation of LAlS as the only product soluble in organic solvents. Both of them represent rare examples of aluminum polysulfides. All compounds were characterized by spectroscopic methods and single crystal X-ray diffraction studies.
