Competing Magnetic Interactions in a Dinuclear Ni(II) Complex: Antiferromagnetic O−H···O Moiety and Ferromagnetic N₃^- Ligand

Synthesis, structural characteristics, magnetic studies and DFT calculations in Ni(II) dinuclear complexes containing two bridging N3- and an O−H···O linkage reveal the existence of ferromagnetic interactions between Ni(II) centers via N3- ligands and antiferromagntic interactions through the H-bonded moiety. The overall magnetic behavior of the system depends on the delicate balance between these two competing interactions.
