Schiff base ligand salpphen (L) were synthesized by the condensation reaction of p-phenylenediamine with salicylaldehyde, Schiff base ligand was used as a primary ligand and some of amino acid (Alanine or Glycine) as secondary ligand to synthesized complexes containing mixed ligands with the metals ions Co(II), Ni(II), Cu(II) . The prepared ligand(L) was characterized on the basis elemental analyses(CHN), FT-IR,1HNMR, UV-Visible spectroscopy. While prepared complexes were characterized on the basis elemental analyses, FT-IR, 1HNMR, UV-Visible spectroscopy, conductivity and magnetic measurements. The morphology of the one of the complexes CuLAla was studied by scanning electron microscopy (SEM). The compounds were subjected to simultaneous thermogravimetric analysis (TGA/DTA) to study their decomposition mechanism and thermal stability. The spectroscopic and magnetic moments shows the suggested geometry of the metal ions complexes are octahedral. The antibacterial activities of the ligand and some of its metal complexes have been screened against bacteria E. coli and S. aureus.
