In this work the preparation and characterization  of tetradentate ligand (H2L).The ligand obtained from the reaction of benzidine with 2-benzoyl benzoic acid .The synthesized ligand(H2L) was characterized by UV-Vis , FT-IR spectroscopy, 1H,13 C-NMR spectra, melting point and (C.H.N).The mixed ligand complexes were synthesis from ligand(H2L)was used as a primary ligand while 1,10-phenanthrolineligand (phen)was used as a secondary ligand with metal ion (M(II) : Cu(II),Co(II), Mn(II) ,Ni(II) and Hg(II)). All the complexes were characterized by UV-Vis, FT-IR spectroscopy methods, elemental analysis (A.A), melting point measurements, conductivity and magnetic susceptibility. These measurements showed tetrahadral geometry around (Mn and Ni) ions and square planer geometry around (Co, Cu and Hg) ions.The antibacterial activity of (H2L) and [M2(phen)2(L)]Cl2] complexes  in molar ratio [2:2:1] [M:(phn):L] were studied by using (MIC) inhibition method.


Keywords: Characterization,Schiff bases,2-benzoyl benzoic acid, binuclear complexes, Benzidine and Biological activity.
