Bis(2,2′-bipyridine)(azophenol)- and bis(2,2′-bipyridine)(azonaphthol)ruthenium(II) complexes have been synthesized and characterized by their chromatographic behavior, conductivity, and visible-ultraviolet spectra. These Ru(II) azo ligand derivatives are of particular interest for the characterization of metal-azo protein complexes currently under investigation. A ligand-localized, bathochromically shifted absorption band at 18 000 cm-1 (550 nm) is observed upon Ru(II) complexation of the azo ligands. Analogous behavior has been observed on complexation of azo dyes and azo proteins by Co(III), Co(II), and Zn(II).
