The tridentate (HL) Schiff base was synthesized by reacting 2-quinolinecarboxaldehyde with 3-aminophenol in absolute ethanol. The resulting HL ligand was also coordinated with the Ni(II) and Cd(II) ions. This Schiff base and its Ni(II) and Cd(II) complexes were characterized by multiple and usual methods including the 1H NMR, elemental analysis, FT-IR, UV-Vis, and magnetic moments. It was found that the ligand acts as a tridentate chelate. Both compounds, HL ligand and its Ni(II), Cd(II) complexes were as well tested in biological activity. The obtained results indicate that the Ni(II) complex only exhibit antifungal activity and the two complexes have antibacterial activity towards the same organism studied.
