الملخص العربي
In this work thepreparation and characterization of tetradentate ligand (H2L), from the reaction of benzidine with 2-benzoyl benzoic acidto produce the Schiff base ligand (H2L), was carried out in absolute ethanol as a solvent under reflux .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 primaryligand 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)) at reflux, using ethanol as solvent and KOH as a base. All the complexes were characterized by spectroscopy methods (UV-Vis ,FT-IR spectroscopy) along elemental analysis (A.A) and melting point measurements were carried out, together with 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 inhibition method
