Abstract
Two new binuclear imidazolate bridged complexes, [(PAN)Cu(im)Cu(PAN)](ClO4) (2) and [(PAN)Cu(im)Zn(PAN)](ClO4)(2) (PAN = 1-(2-pyridylazo)-2- naphthol, im = imidazolate) have been prepared. Room temperature magnetic susceptibil ity of [(PAN)Cu(im)Cu(PAN)](ClO4)(2) reveals the presence of intramolecular antiferromagnetic interactions through the imidazolate bridge. X-and EPR s pectra of some Cu-II mononuclear and Cu-Zn binuclear complexes have been re ported. In solution (100%, DMSO, LNT), the imidazolate bridge of the comple x [(PAN)Cu(im)Zn(PAN)(2+) breaks on zinc side. The formation of mononuclear rind binuclear complexes has been confirmed by spectrometry.
