Abstract
Reaction of 2-(arylazo)phenols with [Ru(PPh3)2(CO)2Cl2] affords a family of organometallic complexes of ruthenium(II) of type [Ru(PPh3)2(CO)(CNO-R)], where the 2-(arylazo)phenolate ligand (CNO-R; R = OCH3, CH3, H, Cl, and NO2) is coordinated to the metal center as tridentate C,N,O-donor. Another group of intermediate complexes of type [Ru(PPh3)2(CO)(NO-R)(H)] has also been isolated, where the 2-(arylazo)phenolate ligand (NO-R) is coordinated to the metal center as bidentate N,O-donor. Structures of the [Ru(PPh3)2(CO)(NO-OCH3)(H)] and [Ru(PPh3)2(CO)(CNO-OCH3)] complexes have been determined by X-ray crystallography. All the complexes are diamagnetic and show characteristic 1H NMR signals and intense MLCT transitions in the visible region. Both the [Ru(PPh3)2(CO)(NO-R)(H)] and [Ru(PPh3)2(CO)(CNO-R)] complexes show two oxidative responses on the positive side of SCE.
