Synthesis, Characterization And Biological Evaluation Of Some Metal Complexes Of Transition Metal Ions With Coumarin Schiff Bases Having N And O Donor Atom

The lipophilic nature of the ligands increases due to the introduction of halogen atoms. The presence of halogen atom (Cl, Br, I and F) also increases the bioactivity of those ligands. The core moiety gets enhanced in its bio-activity by the presence of such electronegative atoms. In the present study, some metal complexes of transition metal ions are synthesized using the Schiff base derived from 8- formyl-7-hydroxy-4-methylcoumarin and p-fluoroaniline.
