Abstract

Hexanuclear Cu^II-complexes of formula PPN[Cu₆(µ₃-O)₂(µ-4-Rpz)₆(µ-4-R′-3,5-Ph₂pz)₃] have been structurally characterized and the effect of pyrazole substituents on their two consecutive one-electron oxidation processes, leading to (possibly delocalised) mixed-valent products, has been probed by cyclic voltammetry.
