Biologically active nickel(ll), copper(ll) and zinc(ll) chelates with thiazole-derived nitro- and chlorosalicylaldehyde Schiff-bases having the same metal ion but different anions, e.g. nitrate, sulfate, oxalate and acetate have been synthesized and characterized on the basis of their physical, spectral and analytical data. In order to evaluate the possible participating role of anions on the antibacterial properties, these ligands and their synthesized metal chelates with various anions have been screened against bacterial species Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus.
