A reaction time of 3 hr is required for the synthesis of the binuclear complex. Pentaammine(trifluoromethanesulfonato-0)ruthenium(III) trifluoromethanesul-fonate (0.20 g, 0.31 mmol) is dissolved in degassed (30 min, Ar) acetone (AR, 10 mL) contained in a 50-mL bubble flask (Fig. 1) under a continuous stream of At. ( Caution. Acetone is highly flammable and toxic. Due care should... 

Osmium and ruthenium polypyridine complexes initially received much attention from Dwyer and coworkers because the M(II), M(III), and M(IV) oxidation states are substitution inert.Interest in them has been renewed because of their photochemical reactions and the role they play in the study of reactions of coordinated ligands " and of mixed valence ions and in the preparation of electroactive polymer films. The aqua complexes " also have important potential applications in the selective oxidation of organic molecules and water. We found that trifluoromethanesulfonato (triflato) complexes are convenient synthetic intermediates in the preparation of aqua and oxo species, " and we describe the syntheses of the cii-bis(2,2 -bipyridine) complexes here. 

The (2,2 -bipyridine-A(,A( )(2,2 6 2"-terpyridine-A(,yV, yV"),(bpy)(trpy) complexes of ruthenium and osmium, like the bis(2,2 -bipyridine-A(,N ) series, were first studied by Dwyer and coworkers " and are interesting because more than one oxidation state is substitution inert. More recently, these (bpy)(trpy) species have generated interest because the M(IV) oxo complexes are useful oxidants of organic molecules. " The (bpy)(trpy) series of complexes have also proved useful in the study of the redox chemistry of coordinated ligands. The (bpy)(trpy) and bis(bpy) complexes containing the coordinated trifluoromethanesulfonato (triflato) ligands are useful precursors to a variety of complexes. The syntheses of these species and the aqua complexes derived from them are reported here.
