| Abstract | ||
| A new mix ligand complexes were synthesized using the prepared Schiff base (BM) as a primary ligand and 8-hydroxy quinoline(HQ.) as a secondary ligand with metal ions [V(III), Cr(III), Fe(III), Rh(III) and Al(III)] .These complexes were characterized by (FT-IR and Uv-Vis) Spectroscopies , (elemental analysis and flame atomic absorption) techniques as well as (magnetic susceptibility and conductivity) measurements. showed that the metal ions was coordinated with (BM) by nitrogen atom of azomethene groups and oxygen atom of hydroxyl groups , in addition of coordination of (HQ.) by oxygen atom of hydroxyl group and nitrogen atom of the quinoline ring. The antibacterial activity for ligands (BM and HQ.) and mixed ligand complexes were studied against two selected micro-organisms (Escherichia coil ) and (staphylococcus aureus).The antifungal activity against two micro-organism (penicillumSpp and Aspergillusflavus) were studied for ligands (BM and HQ.) and mixed ligand complexes . The results showed great enhancement of activity of the all complexes relative to that of their respective ligands. | ||
