New ruthenium polypyridyl complexes were synthesized and characterized, showing potential applications in detecting acetonitrile contaminants and catalyzing water oxidation processes.
New ruthenium(II) polypyridyl complexes of formulae [RuCl(Me(2)Ntrpy)(bpy-OMe)]Cl, 1, and [Ru(Me(2)Ntrpy)(bpy-OMe)(OH2)](CF3SO3)(2), 2, with Me(2)Ntrpy = 4'-N,N-dimethylamino-2,2':6',2 ''-terpyridine and bpy-OMe = 4,4'-dimethoxy-2,2'-bipyridine, were synthetized and characterized by spectroscopic and electrochemical techniques. Besides, [Ru(Me(2)Ntrpy)(bpy-OMe)(NCCH3)](2+), 3, was obtained and characterized by UV-vis spectroscopy in acetonitrile solution. All experimental results were complemented with DFT and TD-DFT calculations. The complete structure of complex 1 was determined by X-ray diffraction, evidencing that the Ru-N and Ru-Cl bond lengths are longer than those determined in [RuCl(trpy)(bpy)](PF6). The strong electron donating properties of the substituents of both bpy and trpy rings in complexes 1 and 2 led to their potential applications for detecting traces of acetonitrile as a contaminant in aqueous solutions of radiopharmaceuticals and to utilization of complex 2 as a promising candidate for catalyzing water oxidation processes.
