Study of Electrochemical and Electronical Properties on the Some Schiff Base Ni Complexes in DMSO Solvent by Computational Methods

Abstract

In this study, the quantum mechanics calculations were performed on M(Chel) where M=Ni(II) and Chel=BAE(bis-acetylacetone ethylenedimine), BFE= bis(1,1,1-triflouroacetylacetone) ethylenedimine and BCE=bis(3-chloroacetylacetone)ethylenedimine) ligands using Gaussian 03 and hartree-fock theory (HF) at B3LYP/6-311G level in the gas phase and solution phase were applied. The polarized continuum model (PCM) is used to calculate salvation energies. After optimizing, various parameters such as electrode potentials, energy gap, chemical hardness, chemical potential and electrophilicity in solvent (DMSO) have been calculated. It was found to be planar and four-coordinate. Reduction potentials toward a given M(II), according to the Schiff base ligands, were changed in the trend: BAE>BCE>BFE.
