Mixed-ligand silver(I) complexes containing bis[2-(diphenylphosphino)phenyl]ether and pyridyl ligands

The reaction of [Ag2(κ2-P,P′-DPEphos)2(μ-OTf)2] (1) (DPEphos = bis(2-(diphenylphosphino)phenyl]ether) with 1,10-phenanthroline (phen) and 4,4′-bipyridine in equimolar ratios afford, respectively, the mononuclear complex [Ag(κ2-P,P′-DPEphos)(phen)][OTf] (2) and the coordination polymer [Ag(κ2-P,P′-DPEphos)(μ-4,4′-bpy)]n[OTf]n (3). In complex 3, the silver atoms are bridged by 4,4′-bipyridine units to form a zigzag metallopolymer.

Mixed-ligand silver complexes containing DPEphos, 1,10-phenanthroline and 4,4′-bipyridine have been synthesized and structurally characterized.Figure optionsDownload as PowerPoint slide
