Abstract
The paramagnetic complex, (L2-.bul.) RuII(bpy)2, where L2-.bul. = 5-methyl-2-oxido-1,4-benzosemiquinone and bpy = 2,2'-bipyridine, was studied because the quinonoid form, LH, is a model of the topaquinone (TPQ) cofactor of certain Cu-dependent amine oxidases. For the metal complex, the potential ortho- and para-quinoid character of the LHn system was probed by high-resoln. EPR spectroscopy of the semiquinone state which could be obtained through oxidn. of the basic catecholate form. on SciFinder(R)
