title: Trigonal-prismatic CuII6-pyrazolato cages: structural and electrochemical study, evidence of charge delocalisation.
abstract: Hexanuclear CuII-complexes of formula PPN[Cu6(micro3-O)2(micro-4-Rpz)6(micro-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.
