Synthesis and characterization of silver(I) salts with amino methyl pyridines containing phosphines: novel complex formation upon ratio, anion, or ligand changes.

Phosphorus ligands are well recognized for stabilizing metal complexes in a variety of oxidation states and coordination geometries.1 Compounds with pyridyl containing phosphines have been investigated with carbinol groups in the past; this work studies the pyridyl amines. The focus of this research is to explore the different binding properties as the position of the nitrogen changes on the ligand, as well as changing the silver(I) salts binding to the ligand such as the BF₄⁻ , OTf⁻ and the tfa⁻ anions. The synthesis and characterization of two new ligands that are from the same family have been looked at, and the synthesis of novel silver(I) complexes involving these ligands have been explored. All of the compounds produced have been characterized by X-ray crystallography, NMR spectroscopy, fluorescence, and elemental analyses.
