Multifunctional phosphines such as trispyridylphosphine have the potential to bind to two or more metal ions; however, few examples of structural characterization of these ligands in bimetallic complexes exist in the literature, and even fewer examples exist that examine the influence of an N-coordinated metal on P-coordination to another metal, or the effect(s) of substitution of the pyridyl ring on P,N donor strength. Presented here is synthetic, structural and spectroscopic details of several (PyR)3P–AuCl complexes, where PyR represents the substituted pyridine. Additionally, we present bimetallic complexes Cu(I)X(PyR)3P–AuCl. These complexes have shown to fluoresce in solution and in the solid state, and N,N,N coordination of Cu(I) to the (PyR)3P–AuCl complexes shifts the fluorescence. We suggest the effects that contribute most strongly to the physical and electronic properties of metal-ligand complexes of this type.
