Cage-Type Hexacopper(II) Complex Formed by Chloride Template

Abstract A novel cage complex [Cu6Cl(MeO)2(pz)9] (1) was synthesized via a chloride ion template reaction and structurally characterized. In 1, two trinuclear units, {Cu3(MeO)(pz)3}2+, are linked by three pyrazolate ligands, six copper(II) ions form a trigonal prism, and a chloride ion is located at the center of the cage. 1 shows rather strong antiferromagnetic coupling between the copper(II) ions through the MeO− and pyrazolate ligands.
