Abstract

Theoretical study and computational models are capable of reliably predicting ligand selectivity towards variety of metal ions, and can be valuable tools for the advancement of practical works. In this paper, a theoretical study based on the optimum angles and distance between a tetradentate Schiff base ligand and some metal ions is characterized. These investigations are carried out based on ab initio calculations to estimate the pair wise interaction energy between the 2 molecules. The calculations show that the mentioned ligand is a suitable ligand for the extraction of Mn(II) ions from a mixture of Ba(II), Mg(II), Mn(II), Ca(II) and Ni(II) ions.
