The ligand (H2L) Schiff base was synthesized via a reaction of oxo ethanoic acid and Ethane-1,2-diamine environment and characterized by different techniques such as: (1H-N.M.R, C.H.N, UV-Vis, and FTIR). 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- Phenanthroline and ligand. The preparation mixed ligand complexes were diagnosed with different techniques such as :( micro-elemental analysis, molar conductance, atomic absorption, UV-Vis, FT-IR, and magnetic susceptibility). Based on the products that characterized its 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 to coordination with 1,10-Phenanthronline by nitrogen atoms. All complexes showed antibacterial activity toward two types Gram-positive and two types (Gram-negative bacteria.
