Abstract

The use of di-2-pyridyl ketone oxime (Hpko)/X? “blends” (X? = OH?, Cl?, ClO4?) in copper chemistry has yielded neutral binuclear and cationic trinuclear, pentanuclear or hexanuclear complexes. Various synthetic procedures have led to the synthesis of compounds [Cu5(pko)7]·[ClO4]3·2CH3OH·2H2O (1), [Cu3(pko)3(OH)(Cl)]2[Ph4B]2·4DMF·2H2O (2), [Cu2(pko)4] (3), {[Cu6(pko)6ClO4(CH3CN)6][Cu6(pko)6(ClO4)3(CH3CN)4]}·8ClO4·14CH3CN·H2O (4). The structures of the complexes have been determined by single-crystal X-ray crystallography.
