Abstract

Several Schiff base have been studied in the past because of their wide applicability. The derivatives of such compounds and their metal complexes, and also after suitable structural modifications, may be used as bioactive materials for medicines, biological, pharmacological, clinical and analytical applications. Metal complexes with symmetric compartmental ligands have been the focus of extensive studies because of their applications in several areas of chemical research. Schiff bases play a central role as chelating agents for a large number of metal ions, as they form stable complex with the metal ions. 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)-3-(2- nitrophenyl)allylidene)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 notable 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. Theoretical data results pseudo –tetrahedral geometry for complexes.
