الملخص العربي
The ligand (H2L) Schiff base was synthesized via a reaction of oxoethanoic acid and Ethane-1,2-diamine environment, and characterized with different techniques such as: (1H&13C-N.M.R, C.H.N, UV-Vis and FT-IR). Mixed ligands complexes of some metal ions [Hg(II), Cu(II),Mn(II), Ni(II), and Co(II)] were prepared by the reaction of 1,10-Phenanthronline and ligand. The preparation mixed ligand-complexes were diagnosedwith different techniques such as :( micro elemental analysis, molar conductance, atomic absorption, UV-Vis, FT-IR, and magnetic susceptibility). Based on the products thatcharacterizedits geometric arrangement is octahedral that the metal ions was coordinated with (H2L) by two oxygen atoms of carboxyl groups and two nitrogen atoms of imine groups in mixed ligand complexes, in addition of coordination with 1,10-Phenanthronline by nitrogen atoms. The all complexes showed antibacterial activity toward two types Gram positive and two types (Gram negative bacteria.
