Abstract

Treatment of [Os(bpy)2Cl2] (bpy = 2,2′-bipyridine) with 2-aminoethanethiolate was accompanied by air oxidation to give [Os(2-aminoethanesulfinato-N,S)(bpy)2]+ ([1]+), which was further oxidized by air to be converted into [Os(2-iminoethanesulfinato-N,S)(bpy)2]+ ([2]+) under photoirradiation. Complex [2]+ was reverted back to [1]+ by treatment with BH4−.
