Ruthenium(II) Complexes of Chelating Ligands Containing Benzoxazole and Benzothiazole Subunits: Synthesis, X-Ray Crystallography, Spectroscopy, and Electrochemistry

Abstract

Bis(2,2′-bipyridyl)ruthenium(ii) complexes of four chelating ligands that contain benzoxazole or benzothiazole rings have been prepared and characterized by NMR spectroscopy, visible absorption spectroscopy, electrochemical measurements and, in two cases, by X-ray crystallography. The incorporation of these ring systems has a marked effect on the electronic properties of the resulting complexes.
