Abstract

The field of Schiff base complexes was fast developing on account of the wide variety of possible structures for the ligands depending upon the carbonyl compounds and primary amines. Many tries were performed to synthesize symmetric or asymmetric ligands in order to obtain rare coordination number with mercury and cadmium ions whose importance was mainly due to their ability to form metal coordination compounds. Recently group XII metal complexes, which contain a stable d10 electronic configuration, have received a lot of attention in the fields of inorganic chemistry, biochemistry and environmental chemistry. In this work we wish to report the synthesis of some new four coordinated complexes of zinc halides with the ligand of N,N′-bis((E)-4- flourobenzylidene)ethylenediamine. The ligand and complexes were full characterized by physical and spectral data including microanalysis, FT-IR, UV-Vis, 1H and 13C NMR and conductivity measurements. The analytical data results the 1:1 ratio between the ligand and related salts. The considerable changes in the UV-Vis, IR and NMR spectra confirm the coordination of ligand. Finally, optimized structures, molecular parameters and vibrational frequencies were calculated at the B3LYP/LANL2DZ level of theory.
