5 ligands were prepared by the condensation of 1,10-phenanthroline-5,6-dione with 2,4,6-Trihydroxy benzaldehyde, 5-Bromo,3-methoxy benzaldehyde ,2,4,6-Trifluro Benzaldehyde,4-Ethyl Benzaldehyde,4-Hydroxy 3,5-dimethyl Benzaldehyde respectively. The structures of the compounds were determined by elemental analyses, IR, UV-Visible, 1H-NMR and Mass Spectra. Antibacterial activity of the ligands and their metal complexes were tested against selected bacteria by disc diffusion method.
