| Abstract | ||
| Phenylalanine amino acid was condensed with 2-hydroxybezaldehyde to give the Schiff base sodium 2-(2-hydroxybenzylideneamino)-3-phenylpropanoate, which was used as a ligand [HL] type (NO) in complexation with some metal (II) chloride MCI2, where [M= Co(II), Ni(II), Cu(II) and Zn(II)], in basic media, to give Na2[M(L2)] complexes. The Schiff base ligand and All complexes were characterized by spectroscopic methods, [FTIR, UV-Vis, atomic absorption], melting point, chloride content, conductivity and magnetic susceptibility measurements, molar ratio, as well as the [HL] ligand characterized by 1H NMR spectral. The data, of these studies and measurements suggest an octahedral geometry around Co(II), Ni(II), Cu(II) and Zn(II) ions. The synthesized ligand, along with their metal complexes, was screened for in vitro antibacterial activity against gram-negative bacteria like E. coli, Pseudomonas, and gram-positive bacteria like Staphylococcus aureus. | ||
