Synthesis, characterization, theoretical calculation and antimicrobial properties of some new cadmium halide complexes

The scientific field of Schiff bases and their complexes is interesting in inorganic chemistry points of view. These compounds have a variety of structures and applications depending on the aldehyde and amine used in their synthesis. These ligands and their metal complexes have different applications in bioinorganic chemistry, material science, catalysis, separation and encapsulation processes, hydrometallurgy, formation of compounds with unusual properties and metal–metal interactions. Many biologically active Schiff bases have been reported in the literature that show antimicrobial, antibacterial, antifungal, anti-inflammatory, anticonvulsant, antitumor and anti HIV activities[1-3]. In this work, we present synthesis and characterization of some cadmium halide complexes with formula of CdLX2 ((X= Clˉ , Brˉ,Iˉ and L= a new ligand formed via condensation of bromobenzaldehyde and bis(2-aminoethyl)amine). The ligand and its complexes were characterized by physical and spectral data. After characterization, the ligand and its complexes have been subjected to biological standard tests for their antimicrobial activities. Finally, the compound structures were optimized and then some structural parameters and vibrational frequencies were calculated at the B3LYP/LANL2DZ level of theory
