| Abstract: | The reaction of the complex Au2Ag2(C6F5)4)Ntriple bond]CCH3)2]n (1) with 1 equiv of CuCl in the presence of 1 equiv of pyrimidine ligand leads to the formation of the heteronuclear Au(I)-Cu(I) organometallic polymer Cu{Au(C6F5)2}(Ntriple bond]CCH3)(mu2-C4H4N2)]n (2) through a transmetalation reaction. Complex 2 displays unprecedented unsupported Au(I)...Cu(I) interactions of Au(C6F5)2]- units with the acid Cu(I) sites in a Cu(Ntriple bond]CCH3)(mu2-pyrimidine)]n+(n) polymeric chain. Complex 2 has a rich photophysics in solution and in the solid state. |
