dc.titleMixed ligand Ru(II) complexes with 2,2 '-bipyridine and 2-(2 '-pyridyl)quinoxalineen
heal.abstractThe synthesis and the physical properties of a new series of Ru(II) mixed ligand tris chelate complexes of the type [LxRu(bpy)(3-x)], where L = 2-(2'-pyridyl) quinoxaline and bpy = 2,2'-bipyridine, are reported. The complexes were fully characterized by NMR spectroscopic techniques, Electrospray Mass Spectroscopy, UV-visible spectra and elemental analyses. The complex [RuL3](PF6)(2) probably has the mer conformation due to the bulky shape of the L on the side of quinoxaline. The complex [RuL2(bpy)](PF6)(2) was isolated as a mixture of all three possible geometric isomers, while the [RuL(bpy)(2)](PF6)(2) in only one isomer as theoretically expected. Photoinduced dissociation of one molecule of the ligand L from the complex [RuL3](PF6)(2) upon exposure to room light has been studied by H-1 NMR and UV-vis Spectroscopies.
