Some new complexes of Schiff base ligand derived from sulfadiazine and terephthaldyhyde with Cu(II),Ni(II) ,Fe(II) ions were synthesizedand characterized by UV-Vis spectral analysis, Fourier transform infrared spectroscopy (FT-IR), H1 – NMR ,biological activity The UV-Visible spectrophotometric analysis revealed 1:2 (metal-ligand) stoichiometry for all complexes and assigned an octahedral geometry.while the appearance of ν(O-H) due to water moleculesin all complexes and the lowering shift of the stretching frequency of the ν(CH=N) azomethine band in the ligand after complexation, the schiff base ligand showed higher significant activity against one or more bacterial compared with complexes.
