A mixed‐valent redox‐active copper thiolate complex is formed in the reaction of [Cu(MeCN)4]PF6 with a CPh3 thioether by a combination of homo‐ and heterolytic cleavage of the SCPh3 bond. In its oxidized state, the hexanuclear copper sulfur cluster (see picture) has the same average metal oxidation state as the dinuclear copper thiolate center of cytochrome c oxidase or N2O reductase.
