RuII(bmaa-)(bpy)2(PF6) 1(PF6), RuII(bmaa-)(Cym)Cl (2), and RuII(bmaa-)(Cym)(py)(PF6) 3(PF6) bmaa- = N,N'-bis(4-methoxyphenyl)acetamidinato, bpy = 2,2'-bipyridine, Cym = p-cymene, py = pyridine were studied spectroelectrochem. (EPR, UV/visible) to reveal metal-centered oxidn. for 1+ but bmaa--based oxidn. to yield amidinyl ligands in 2+ and 32+. on SciFinder(R)
