Characterization and biological effectiveness of synthesized complexes of Palladium (II) from imine compounds

Abstract

This article involved synthesize a novel Palladium (II) complexes as follows: The imine compounds were prepared by reacting of aldehydes with nitrogen compounds: 4-methylbenzene-1,2-diamine, naphthalene-1,8- diamine, and 4-chloro-5-methyl benzene -1,2-di amine and sublimated into ethanol. The reaction was continued by the thin layer chromatography (TLC), where the imine compounds were determined by spectrophotometry of FT-IR UV-Visible, 1H-NMR. The palladium complexes were synthesized by the reaction of the prepared imine compounds (after they were dissolved) using absolute ethanol and palladium salt (PdCl2), which was dissolved by using absolute ethanol with 4 drops of 11.6 N of HCl acid, then the mixture was raised for 3 hours. When the amine compounds reacted with the Palladium ion (II), this interaction leads to formation of palladium complexes, the reaction was continued by the thin layer chromatography (TLC), the complexes were spectrophotometrically characterized by measurement the ultraviolet-visible, infrared rays, mass spectrometry and molar conductivity. The geometric shape of the complexes had been proven, which the palladium complexes have a square planer shape. The biological activity of some synthesized complexes was determined using two different types of bacteria (Gram-Positive and Gram-Negative), namely Staphylococcus Aureus and Escherichia coli. The results show that some concentrations have an intense inhibitory effect on the target bacteria
