An Environmentally Beningn Solvent Free Novel Methods for the Synthesis of Metal Complexes Using Imidazo[4,5-F] 1,10- Phenanthroline and their Derivatives and Biological Activities

MnL,CuL,CoL,NiL,CrL,FeL and ZnL (L = [2,4,6-trihydroxy phenyl ] Imidazo[4,5] 1,10phenanthroline),MnL 2 ,CuL 2 ,CoL 2 ,NiL 2 ,CrL 2 ,FeL 2 and ZnL 2 (L 2 = (5-Bromo,3-Methoxy Phenyl) Imidazo [4,5] 1,10Phenanthroline), MnL,CuL,CoL,NiL,CrL,FeL and ZnL (L=2,4,6-trifluro phenyl Imidazo [4,5] 1,10-phenanthroline), MnL,CuL,CoL,NiL,CrL,FeL and ZnL (L=4-ethyl phenyl Imidazo[4,5] 1,10-phenanthroline), MnL,CuL,CoL,NiL,CrL,FeL and ZnL (L=4-hydroxy,3,5-dimethyl phenyl Imidazo[4,5] 1,10-phenanthroline) complexes were synthesized. L, L,L,L and L ligands were prepared by the condensation of 1,10-phenanthroline-5,6-dione with 2,4,6-Trihydroxy benzaldehyde, 5-Bromo,3methoxy 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.
