Thiosemicarbazide and aromatic aldehyde are used to create the Schiff bases (L1, L2). Cu (II), Co, and Ni ions were added to these ligands to further complex them. Measurements of conductance, magnetic susceptibility, and Fourier transform infrared (FTIR) and H1NMR spectra have all been used to characterize the compounds. The ligands' spectrum data and density function theory were found to be in good agreement with their structures, demonstrating the great purity of every molecule.
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.
