Reversible ligand‐centered one‐electron oxidation of square‐planar neutral complexes of palladium( II ) and platinum( II ) [M(bpy)(L)] (bpy=bipyridine, L: see picture) leads to the paramagnetic complexes [M(bpy)(L . )] + . Thus, the existence of S,S‐coordinated o ‐dithiobenzosemiquinonate(1−) π radical ions has been proven unequivocally.
