A series of copper(II) complexes with pyridine-phenol-based N,O/donor ligands has been synthesized and structurally characterized. Slight variations of one of the building blocks (namely, the ligand or the counterion) lead to drastic changes in the nature of the resulting coordination assemblies. Indeed, depending on the anions involved and on a minor modification of the ligand, a dinuclear, a one-dimensional chain, or two cubane copper structures are obtained. The magnetic properties of all polynuclear copper(II) compounds have been investigated, which show that the different clusters exhibit antiferromagnetic interactions.
