5 ligands were prepared by the condensation of 1,10-phenanthroline-5,6-dione with 2-hydroxy-4-methoxybenzaldehyde, paramethyl benzaldehyde ,2,4,6-Trimethoxy Benzaldehyde,4-Fluro Benzaldehyde,4-Hydroxy 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.
