The compounds [Ru II (bmaa – )(bpy) 2 ](PF 6 ) [ 1 (PF 6 )], [Ru II (bmaa – )(Cym)Cl] ( 2 ), and [Ru II (bmaa – )(Cym)(py)](PF 6 ) [ 3 (PF 6 )] [bmaa – = N , N ′‐bis(4‐methoxyphenyl)acetamidinato, bpy = 2,2'‐bipyridine, Cym = p ‐cymene, py = pyridine] were studied spectroelectrochemically (EPR, UV/Vis) to reveal metal‐centered oxidation for 1 + but bmaa – ‐based oxidation to yield amidinyl ligands in 2 + and 3 2+ .
