Unsupported gold(I)-copper(I) interactions through eta(1) (Au)-[AU(C6F5)(2)](-) coordination to Cu+ lewis acid sites
The reaction of the complex [AU(2)Ag(2)(C6F5)(4)(NdropCCH(3))(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)}(NdropCCH(3))(mu(2)-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(NdropCCH(3))(mu(2)-pyrimidine)](n)(n+) polymeric chain. Complex 2 has a rich photophysics in solution and in the solid state.
