Abstract

Coupling reaction between the diazonium salt of 3-chloro-4- fluoroaniline and 4-methyl imidazole used to create new Azoimidazole compound (4MCFD). Solid complexes of this ligand and series of transition metal ion were synthesized. The complexes and ligand were characterized by Mass Spectroscopy, 1H-NMR,13C-NMR, FT-IR, UV-Vis, Elemental Analysis, Molar Conductivity, and their inhibition ability against E. coli, P. aeruginosa, K. pneumonia, and S. aureus bacteria studied, according to the common chemical characterization methods. The values of stability constants were also calculated and showed high level of stability. All of the synthesized complexes have octahedral geometry with general formula [M(4MCFD)2Cl2], (4MCFD) ligand behave as a bidentate. New ligand and its complexes exhibited significant inhibitory efficacy against gram-negative bacteria as compared to positive bacteria.
