Synthesis, Chemical Characterization, and Bacterial Inhibition Studying of New Mixed Ligand Complexes of 4-Methylimidazoleazo Ligand, and Ethylenediamine with Some Divalent Metal Ions

Abstract

New synthesized series of mixed ligand complex prepared for Co (II), Ni (II), Cu (II), Cd (II), and Hg (II) ions, with azo compound derived from 4-methylimidazole as a primary ligand (TBPAM) , and ethylene diamine as a secondary ligand. Mass , 1HNMR, C.H.N, Uv-Vis, FT-IR, Atomic Absorption, Molar Conductivity, and Magnetic Susceptibility techniques were used to characterize the complexes, the results were indicated the octahedral geometry with a general formula [M(TBPAM)(en) Cl2] for all complexes, where primary and secondary ligands behaved as a bidentate, finally a noticeable bacterial inhibition of the complexes and primary ligand at a concentration (100mg/ml) was appeared against complexes against Klebsiella, P.aeruginosa, and S. aureus bacteria Keywords: Mixed ligand; Complexes, Biological investigation; imidazole; ethylenediamine.
