Abstract

A hexadentate Schiff base tripodal ligand is synthesized by the condensation of tris 2-aminoethyl amine with 2-hydroxy-1-naphthaldehyde and characterized by various spectroscopic techniques like UV-VIS, IR, NMR, MASS, and elemental analysis. The solution studies by potentiometric and spectrophotometric methods are done at 25 ± 1°C,  M KCl, to calculate the protonation constants of the ligand and formation constants of metal complexes formed by the ligand with FeIII, AlIII, and CrIII metal ions. The affinity of the ligand towards FeIII is compared with deferiprone a drug applied for iron intoxication and transferrin the main FeIII binding protein in plasma. Structural analysis of the ligand and the metal complexes was done using semiempirical PM6 method. Electronic and IR spectra are calculated by semiempirical methods and compared with experimental one.
