The Trinuclear Copper(I) Thiolate Complexes[Cu3(NGuaS)3]0/1+ and their Dimeric Variants [Cu6(NGuaS)6]1+/2+/3+ with Biomimetic Redox Properties

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 SCPh3 bond. In its oxidized state, the hexanuclear copper sulfur cluster (see picture) has the same average metal oxidation...

Zusammenfassung: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 SCPh3 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.
