Valence tautomerism involving coupled Cu +/2+ and quinone − \. /2− redox systems has been observed for the first time outside an enzymatic situation (amine oxidases) with chelates L as Cu I and Cu II affine coligands. Even slight variations of the quinone substitution pattern suffice to shift the valence tautomer equilibrium completely. [(L)Cu II (Q −II )] ⇌ [(L)Cu I (Q −I )]
