A Crystallographic, EPR and DFT Investigations of a Novel Magnetically Silent Mono-atom Acetate-Bridged Binuclear Schiff Base-Copper(II) Complex

Yeni Bir Manyetik Tek-atom Asetat Köprülü Schiff Bazı -Bakır(II) Kompleksinin Kristallografik, EPR ve DFT ile İncelenmesi

Arecent example of one-atom acetate bridged symmetric dinuclear copper(II) complexes, Di-μ-acetato-bis{1-((pyridin-2-ylmethylimino)methyl)naphthoxo}copper(II) ([Cu2(NP)2(Ac)2]•2MetOH(1)) (HNP=1-((pyridin-2-ylmethylimino)methyl)naphthol)) have been prepared and characterized by X-ray crystallography, Elemental analyses, ESI-mass, UV-Vis and IR spectroscopic techniques. Magnetic properties of the complex have been probed by EPR measurements and the presence of spin-only paramagnetism of the compound with none of significant exchange coupling has been demonstrated unlike ferro or antiferromagnetism that was otherwise observed in all other analogous structures previously reported. The existence of a trivial ferromagnetic exchange which is quantitatively ignorable has been suggested by DFT-Broken Symmetry calculations performed at crystallographically characterized experimental geometry.
