Abstract
The work aimed to prepare and characterize new Schiff -base ligands and their metal complexes aiming to study their effects in the treatment of tumor The Ph.D. thesis includes Four main chapters I- Introduction This chapter includes an overview of previous researches for complexes of Schiff-base ligands and their applications II- Experimental This chapter contains the chemical and instruments used in Practical part of thesis as follow: 1) Preparation of the Schiff- base ligands and their metal complexes. 2) characterization of the ligands and their complexes using: • Physical techniques such as molar conductance and magnetic susceptibility • Elemental analyses (C, H, N, Cl and M). • Spectral techniques as IR, UV- Vis., 1H-NMR, mass spectra and ESR measurements.
