Abstract

Two Schiff base ligands are prepared by condensation reaction of ethylenediamine with benzaldehyde or 4-chlorobenzaldehyde in the ratio of 1:2. The metal complexes are prepared by the template method in the ratio of 1:2:1 (ethylenediamine: 4-chlorobenzaldehyde: Zn(II) acetate dehydrate or Ni(II) acetate tetrahydrate). The complexes of the Schiff base N,N’-bis-(4-chlorobenzylidene)ethylenediamine with Zn(II) is successfully prepared. Complexes and ligands are then characterized by elemental analysis, IR spectroscopy, 1H NMR spectroscopy and magnetic susceptibility. The resultssuggested that the structure of Schiff base metal complexes is a polymeric coordination compound of the [Zn(cbaen)2]. A new type of Schiff base Ni(II) complex is successfully prepared with the suggested formula of [Ni(cba)2(en)(H2O)2].H2O. The antimicrobial studies are successfully conducted. Both the Schiff base ligands N,N’-(dibenzylidene)ethylenediamine and N,N’-bis-(4-chlorobenzylidene)ethylenediamine have inhibiting properties while the Zn(II) complex show higher antimicrobial compared to the Ni(II) complex.
