Abstract

By X-ray diffraction analysis, we have established the structure of a binuclear complex of nickel(II) with an azacyclam ligand and a bridging oxalate ion. Study of the magnetic properties of a series of complexes of this type with related macrocyclic ligands has allowed us to observe antiferromagnetic coupling between the metal ions and a magnitude of the exchange integral J that varies in the range from -11.8 cm-1 to -25.6 cm-1. We have shown that, despite the close structural parameters of the macrocyclic ligands, the complexes are characterized by different magnetochemical behavior.
