Synthesis, Characterization, Antimicrobial, and Antioxidant Studies of New Schiff Base Ligands and Their Complexes with Copper Ion
Keywords:
Schiff base, ligand, complex, characterization, antioxidant, antibacterialAbstract
The Schiff bases (L1, L2, L3) were prepared by using 2-Aminobenzyleamine with aromatic aldehyde. These ligands were further complexed with Cu(II) ion. The compounds have been characterization on the basis their spectra of H1NMR, mas, Fourier transform infrared (FTIR), as well as magnetic susceptibillty, elemental analysis (CHN) and conductance measurements. Elemental analysis and spectral data of the ligands were found to be in good agreement with their structures, indicating high purity of all the compounds. The program of Hyperchem 8 have been used for theoretical accounts using PM3 method to study the electrostatic potential that provided good information about the complexity site. Of the result obtained we can suggest square planer geometry for Cu(ІІ) complexes. The antioxidant activity of the syntheses compounds was evaluated by DPPH scavenger and these were showed a good antioxidant activity. All ligands and their complexes were screened for antimicrobial activity, and these compounds showed a good antibacterial activity.
