Abstract Imine ligands are excellent coordinating ligands. Their importance is due to from stable complexes easily with a variety of metal ions. During the past three decades, considerable attention has been paid to the chemistry of the complexes of the imine ligands containing nitrogen and other donors. This attributed to their stability, biological activity and potential applications in many fields making the behavior of imine complexes with transition metals a worthy research topic. The coordination chemistry of imine ligand is also of considerable interest due to interesting applications in medicine, material science and catalysis. Transition metal complexes of imines are one of the most adaptable and thoroughly studied systems. Thus,the scope of the present thesis is to Preparation of some tri and tetradentate ligands containing 5- bromosalicyaldehyde, isatin or 2-hydroxy-1-napthaldehyde (carbonyl group) with 2-aminopyridine or 4-nitro-ophenylenediamine (amino group). Using the prepared ligands to prepare of some novel complexes of some transition element such as Cr(III), Fe(II), Co(II), Ni(II)Imine ligands are excellent coordinating ligands.
