| Popis: | A novel macrocyclic Schiff base ligand 1,4,8,11-tetraaza-2,3,9,10-tetramethyl cyclotetradeca-1,3,8,10-tetraene was synthesized by condensation between butane-2,3-dione and propane-1,3-diamine in an alcoholic medium. The complexes of Co(II), Ni(II), Cu(II) and Zn(II) with Schiff base have been prepared from metal salts in an alcoholic medium. The synthesized Schiff base and its metal complexes are characterized by elemental analysis, molar conductance measurements, magnetic susceptibility, FTIR and electronic absorption spectral data. The higher molar conductance values of these metal complexes show their electrolytic nature. The Schiff base behaves as tetradentate ligand. The general molecular formula of the metal complexes has been found to be [M(L)(X)2] where M= Co(II), Ni(II), Cu(II) and Zn(II) , L=Schiff base and X= water, chlorine and ethanol . Thus, on the basis of elemental analysis and spectral studies octahedral geometry was assigned to metal complexes. The synthesized metal complexes showed more antimicrobial activity than free Schiff base ligand. |
