Abstract

Salicylaldehyde semicarbazone ligand and its Cu (II) complex have been synthesized and characterized by a range of physicochemical methods. Experimental data shows the complex is monomeric and the copper atom is four coordinated in a square planar geometry. The ligand chelates the copper in a tridentate fashion through the carbonyl O,  imine N, and phenolato O with the fourth position being occupied by coordinated Cl. Antibacterial activity of the  prepared compounds was tested against the microbes Enterobacter Aerogenes and Bacillus Cereus. The metal complex showed higher antibacterial activity than the free ligand.

Antibacterial activity complexation semicarbazone tridentate ligand.
