The reaction of benzene-1,2-diamine( o -phenylenediamine) derivatives with anthranilic acid (Ant) yield 2-(1 H -benzimidazol-2-yl)aniline derivatives (BIAD) as (primary ligands) in Effective and appropriate solvent, which confirmed by FT-IR, Elemental analyses (C. H. N, O) and 1 H NMR spectral. These ligands coordinated with some transition metal ions (Co II ,Ni II , Cu II , Zn II ) and anthranilic acid as (secondary ligand) at the (1 : 1 : 1) ratio of the components to yielded a mixed-ligand complexes. All complexes have been studied by IR spectra, 1 H NMR, Elemental analyses (C. H. N. O), atomic absorption, molar conductivity and magnetic moment. Ligands produce chelates with (1;1;1) (metal; ligands; ligand) interactive elements. From all results was suggested that octahedral geometry to complexes and have the formulae [M(BIAD)(Ant)(H 2 O) 2 ] 2- where M = Co (II) , Ni (II) , Cu (II) and Zn (II) .Read More
