Abstract:
The new bidentate Schiff base ligand namely [(E)-N¹-(4-methoxy benzylidene) benzene-1, 2-diamine] was prepared from condensation of 4-Methoxy benzaldehyde with O-Phenylene diamine at 1:1 molar ratio in ethanol as a solvent in presence of drops of 48% HBr. The structure of ligand (L) was characterized by, FT-IR, U.V-Vis., ¹H-, ¹³C- NMR spectrophotometer, melting point and elemental microanalysis C.H.N. Metal complexes of the ligand (L) in general molecular formula [M(L)₃], where M= Mn(II), Co(II), Ni(II),Cu(II) and Hg(II); L=(C₁₄H₁₄N₂O) in ratio (1:3)(Metal:Ligand) were synthesized and characterized by Atomic absorption, FT- IR, U.V-Vis. spectra, molar conductivity, chloride content, melting point and magnetic susceptibility from the above data the geometrical formula was octahedral for all complexes. And in vitro tests for antibacterial activity showed that most of the prepared compounds display activity to (Staphylococcusaureus), (Escherichia coli), (Bacillus subtilis) and (Pseudomonas aeruginosa).
