The complex [Ru(azpy)2(bpy)](PF6)2 (azpy=2-(phenylazo)pyridine, bpy=2,2′-bipyridine) was synthesized and characterized by X-ray diffraction analysis. The coordination geometry around ruthenium(II) was distorted octahedral with coordinating from two N-donor centers of bpy and four N-donor centers of two azpy units. The Ru-N (pyridine of azpy) distance was (average, 2.048(4)Å), shorter than the Ru-N (bpy) distance (average, 2.088(4)Å). The average N = N distance in the title compound was 1.278(5)Å, slightly longer than that of the free azpy ligand, 1.248(4)Å. These results confirm that azpy is a stronger π-acceptor than bpy.
