Designed Synthesis of Mononuclear Tris(heteroleptic) Ruthenium Complexes Containing Bidentate Polypyridyl Ligands

摘要: A general synthetic methodology is reported for tris(bidentate)ruthenium(II) complexes containing three different polypyridyl ligands, based on the sequential addition of ligands to oligomer [Ru(CO)₂Cl₂](subscript n). The tris(heteroleptic) were characterized by FAB mass spectrometry and NMR spectroscopy. An X-ray crystal structure determination was made complex, [Ru(Me₂bpy)(phen)(bpa)](PF₆)₂.
