Synthesis, Charactarization, and Biological Activity Study of Some New Metal Ions Complexes with Schiff Base Derived from Vanilin and Ethylenediamine

This study describes preparation a new series of complexes from metal ions Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) with Schiff base (L) derived from condensation of vanillin with ethylenediamine . Structures of the ligands were identified using IR, UV-Vis, Mass, elemental analysis and ۱H-NMR techniques. All prepared complexes have been identified by recording the melting points, conductivity, FT-IR , UV-Vis spectroscopy, metal analysis by atomic absorption, elemental analysis (CHNO) and measuring magnetic and. All compounds studies biological activity (E. Coli, Staphylococcus aureus, Candida albicans and Aspergillus niger), the activity of bacteria was examined and the results showed that their mineral complexes have good antibacterial activities.
