ABSTRACT
The Schiff base ligand, N,N1-bis(4-nitrobenzylidene) ethylenediamine, has been synthesized by stirring ethylenediamine and 4-nitrobenzaldehyde in ratio 1:2 at room temperature. The ligand was characterized using (FT-IR, UV-vis) spectroscopies, (1H, 13C) NMR spectrum, Mass Spectrum, TGA/DTA and magnetic moments. Matal(II) complexes of the ligand were synthesized in a ratio of 1:2, M:L, and characterized. From elemental analysis data, the metal complexes formed had the general formulae [M(L)2], where L = Schiff base ligand (C16H14N4O4) and M = Mn, Ni and Co. On the basis of FT-IR, and NMR data “N” donor atoms of the Schiff base ligand participated in coordination with metal (II) ions, and thus, a four Keywords: Schiff base, ethylenediamine, antibacterial, metal(II) complex.
