Preparation, identification and biological activity of a new ligand (N, N'-bis (4-Acetamidobenzalidene)‎1,3-diaminopropane)‎ with some transition metal complexes

الملخص EN

-The Schiff base (N,N'-bis (4- Acetamidobenzalidene)1,3-diaminoprobane)was prepared from 4-acetaminobenzaldehyde and 1,3-diaminobrobane by refluxing the two components in methanolic solution.

The metal complexes of Fe(III),Cr(III) Co (II) and Ni (II), were prepared by mixing and refluxing ethanolic solutions of CoCl2. 6H2O,FeCl3.6H2O, CrCl3.6H2Oand NiCl2.6H2O with(N,N'-bis (4- Acetmidobenzalidene)1,3 diaminobrobane).The ligand(L)characterized by Elemental Micro Analysis (CHN) and Nuclear Magnetic Resonance Spectroscopy (1H-NMR) .The ligand(L) and it metal complexes were prepared and characterized by different techniques, such as infrared(IR) (using KBr disc to ligand and CsBr disc to complexes), Mass spectra, and (UV-vis) spectra.The complexes for ligand have shown octahedral configuration, the ligand coordinates with metal through Oxygen and Nitrogen atoms for all complexes and with ratio (1:1).

All the synthesized compounds were tested for their antibacterial activity against Escherichiacoli and Staphylococcus aureusbacteria
