Abstract

KAFI-AHMADI, Leila; MARJANI, Ahmad Poursattar  and  PAKDAMAN-AZARI, Mohammadreza. Synthesis, Characterization and Antibacterial Properties of N,N'-Bis(4-dimethylaminobenzylidene)benzene-1,3-diamine as New Schiff Base Ligand and its Binuclear Zn(II), Cd(II) Complexes. S.Afr.j.chem. (Online) [online]. 2018, vol.71, pp.155-159. ISSN 1996-840X.  http://dx.doi.org/10.17159/0379-4350/2018/v71a20.

We synthesized a new Schiff base ligand by condensation reaction of 4-dimethylaminobenzaldehyde and 1,3-phenylenediamine. Treatment of this Schiff base ligand with Zinc(II) nitrate and Cadmium(II) nitrate in ethanol medium afforded the corresponding metal complexes. The synthesized ligand and complexes were characterized by their UV-Vis, FT-IR and 1H-NMR, 13C-NMR spectral data and elemental analysis. The spectral data suggest an octahedral geometry for these complexes. Antibacterial activities of both synthesized free ligand and complexes were investigated against Escherichia coli, Staphylococcus aureus, and Bacillus subtilis bacteria. The complexes showed better antibacterial activity in comparison with that of the free ligand against selective bacteria.

Keywords : New Schiff base ligand; 4-dimethylaminobenzaldehyde; Zn(II); Cd(II) complexes; antibacterial activity.
