SOME DI- AND TRINUCLEAR ZINC COMPLEXES: ANION INDUCED COMPLEX FORMATION

摘要

Complexes of N,N'-bis(salicylidene)-l,3-diarninopropane, an ONNO type ligand, with ZnX_2(X=AcO~-, NO_3~-, Cl~-, Br~-, l~-) salts were prepared.Molecular structures of these complexes wereidentified using elemental analyses, IR spectrometryand X-ray diffraction techniques. lt has been observedthat the reactions between zinc ions and the said ligandtend to produce polynuclear complexes and depending onthe anion present either di- or trinuclear complexesare formed Thus, it can be deduced from the resultspresented in this article that trinuclear complexesform when the zinc salt used was the acetate or nitrateand dinuclear complexes form if the anion in the zinc salt is a halogen.
