Biologically active triazine-derived NO and NS donor organic ligands and series of their cobalt(II) , copper(TI), nickel(II) and zinc(II) complexes have been synthesized. The ligands have been characterized by their IR H-1-NMR and elemental analysis whereas their metal complexes by conductance and magnetic measurements and elemental and spectral data The synthesized ligands, in comparison to their metal complexes have also been screened for their antibacterial activity against bacterial species Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. The activity data show the metal complexes to be more potent/antibacterial than the parent organic ligands against one or more bacterial species
