عنوان انگلیسی Novel Schiff Base Monoxime Complexes: Synthesis, Characterization, Antibacterial Study, and Surface Properties
چکیده انگلیسی مقاله 2,3-butandionemonoxime and 2-amino-4-nitrophenol were condensed to produce a novel Schiff base ligand (2E,3E)-3-((2-hydroxy-5-nitrophenyl) imion) butan-2-one oxime. In molar ratios of 1:1 and 1:2, Cobalt (II), Nickel (II), Copper (II), Palladium (II), and Platinum (II) complexes have been synthesized by reacting the ligand with metal chloride salts to obtain [Ml. Cl2] and [Ml2.Cl2] complexes. Elemental analysis (C. H. N.), molar conductivity, magnetic susceptibility, and spectral (FT-IR, 13C,
 1H-NMR,1H-1H 2D-NMR (NOE), GC-MS, UV-Visible, and stoichiometry analysis Job`s method) studies were used to characterize all synthesized compounds; the ligand exhibits the formation of a new azomethine (C=N) group, and the Ni(II), Pd(II), and Pt(II) complexes screened as a square planer structure, whereas the Co(II) complex showed as a low-spin octahedral and the Cu(II) complex as a distortion octahedral. The antibacterial activity of the starting material, ligand, and complexes has been examined using the good diffusion method against gram-positive (Staphylococcus aureus) and gram-negative (Escherichia coli) bacteria. According to the activity data, metal complexes and ligands are more active than the starting material, especially the Co(II) complex. Pt (II) complex exhibits the lowest MICs of all the prepared compounds. In this research, we used SEM and EDX methods to investigate the surface properties of the Co (II) complex, which have been particles of nanosize and shape.
