Abstract

A general synthetic methodology is reported for tris(bidentate)ruthenium(II) complexes containing three different polypyridyl ligands, based on the sequential addition of the ligands to the oligomer [Ru(CO)2Cl2]n. The tris-(heteroleptic) complexes were characterized by FAB mass spectrometry and NMR spectroscopy. An X-ray crystal structure determination was made for the complex [Ru(Me2bpy)(phen)(bpa)](PF6)2·C 6H14 [C40H43F12N7P2Ru, M = 1062.8; Me2bpy = 4,4′-dimethyl-2,2′-bipyridine, phen = 1,10-phenanthroline, bpa = bis(2-pyridyl)amine]: triclinic, space group P1, a = 14.57(3) Å, b = 13.50(3) Å, c = 12.73(3) Å, α = 68.6(2)°, β = 63.5(1)°, γ = 79.8(2)°, V = 2082 Å3, Z = 2. Aspects of the electrochemistry, spectroscopy, and photophysics of the tris-(heteroleptic) species are discussed.
