Synthesis, molecular structure determination, and biological studies on E-1-p-ethoxyphenyl-4-hydroximinomethyl imidazole metal complexes

Abstract Metal complexes of E -1- p -ethoxyphenyl-4-hydroximinomethyl imidazole (EALDH) were prepared and characterized by infrared, electronic, 1 H and 13 C NMR two-dimensional spectroscopy, and magnetic and thermal measurements. In all the complexes the organic ligand acts as a chelating agent through N3 imid and N oxime atoms, except in the Ag(I) complex, where the coordination takes place monodentately through the N3 atom of the imidazole. Antimicrobial activities of the complexes against Pseudomonas, E. coli, Proteus, Salmonella, Micrococcus, Staphylococcus, Bacillus , and Candida were performed as a previous step in the study of their biological activities.
