摘要

Two new binuclear imidazolate bridged complexes, [(PAN)Cu(im)Cu(PAN)](ClO_4)_2 and [(PAN)Cu(im)Zn(PAN)](ClO_4)_2 (PAN = 1-(2-pyridylazo)-2-naphthol, im = imidazolate) have been prepared. Room temperature magnetic susceptibility of [(PAN)Cu(im)Cu(PAN)](ClO_4)_2 reveals the presence of intramolecular antiferromagnetic interactions through the imidazolate bridge. X-Band EPR spectra of some Cu~(II) mononuclear and Cu-Zn binuclear complexes have been reported. In solution (100%, DMSO, LNT), the imidazolate bridge of the complex [(PAN)Cu(im)Zn(PAN)]~(2+) breaks on zinc side. The formation of mononuclear and binuclear complexes has been confirmed by spectrometry.
