The present report is concerned with the synthesis novel Schiff base ligand by condense 6-Amino Penicillinic acid with Salicyldehyde. The ligand was characterized by 1H-NMR, 13C-NMR, mass spectrometry, UV-Vis and FT-IR studies. The ligand have got more than one moiety which are capable of chelation, therefore complexes of Co(II), Ni(II), Cu(II), and Zn(II) were prepared. These complexes were characterized by UV-Vis, FT-IR, magnetic susceptibility and Molar conductivity studies. All these techniques indicate 1:2 stoichiometry of synthesized complexes. In all the complexes, Schiff base ligand acts as a tridentate ligand. Finally, the ligand and complexes have been screened for their antibacterial activity against four types of bacteria (Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus facials and Proteus mirabilis) then it isolated from different classes of ulcerative infections while L showed to be tridentate ligand with single negative charge through three active groups, L has been associated with metal ions to form the claw complexes to get octahedral shape. The prepared ligand and its complexes illustrated a good inhibitory ability towards the three varieties bacteria (Staphylococcus aureus, Pseudomonas aeruginosa, and Proteus mirabilis), while the four complexes failed to be suggested in treatment of ulcers that caused by Streptococcus facials. So, the prepared compounds could be good alternatives to the common drugs which are used in treatment of ulcers.
