Abstract

A unique 2:1 cocrystal of mixed Cu(I)/Cu(II) complexes [Cu _I(H₂CPz₂)(MeCN)₂](ClO₄) (1) and [Cu^II(H₂CPz₂)₂(ClO ₄)₂] (4), a novel ferromagnetic ClO₄ ^--bridged bis(μ-hydroxo)dicopper(II) complex, [Cu ₂(H₂CPz₂)₂(OH)₂(ClO ₄)](ClO₄)(CH₃-CN)_0.5 (5), and a bischelated copper(I) complex, [Cu(H₂CPz₂) ₂](ClO₄) (2), prepared from a one-pot reaction of [Cu(MeCN)₄](ClO₄) and H₂CPz₂, are described. The structures of these complexes have been determined by X-ray crystallographic methods. The Cu(I)-N(acetonitrile) bond distances in complex 1 are nonequivalent (1.907(8) and 2.034(9) Å), leading to the dissociation of one MeCN to form a Y-shaped complex, [Cu^I(H₂CPz ₂)(MeCN)](ClO₄) (3), which is oxidized readily in air to form complex 5 with a butterfly Cu₂O₂ core.
