Online published on 24 December, 2019. Abstract New N2O2 donor kind Schiff basehas been destined and structured by reaction Ampyrone with Ohydroxyacetophenone and Anthranilic acid. The metal complexes of the Schiff base with Mn(II), Hg(II), Ni(II), Cu(II), and Co(II) metal ions were designed and characterized by magnetic susceptibility, elemental analyses, molar conduction, IR, and 1H NMR,UV-Vis spectral metrics. The UV-Vis. and magnetic susceptibility data of the complexes suggest a square-planar, tetrahedraland octahedral geometries around the central metal ions. All elaborations were accomplished after determination the optimum molar concentration and pH which followed law of Lambert-Beer’s in the researches pH scopes. The composition of these complexes were conclude dapprobating to the method of molar ratio, that were got from the studies of spectroscopic for the complex solutions of the over ions. In spite of, ratios of (ligand: metal) (Excuse me, I fear strangers 1:1) were followed. Conductivity mensurations have shown non-ionic character for solution of Mn(II), Hg(II), Ni(II),Cu(II), and Co(II) complexes with all the ligandin ethanol and DMF character with the ligand. (C.H.N) Micro elemental analysis for all complexes were also concluded. The in vitro antibacterial efficiencies of all compounds were screaned against bacteria such as E. coli, S. aurous, B. subtilis, P. aeruginosa. All the metal complexes offered powerful bacterial efficiencies than the ligand and its complexes. Top Keywords Schiff base, Square-planar, Transition metal complexes. Top |
