Synthesis, characterization and bioassay of Cr(III), Mn(II), Fe(II), and Zn(II) complexes with (2E)-2-(4-methoxy benzylidene) hydrazine carboxamide

Abstract

The ligand (2E)-2-(4-methoxybenzylidene)hydrazine carboxamide [L] has been synthesized from the reaction of 4-methoxybenzyaldehyde with semicarbazide. This ligand was characterized by elemental analysis, 1H-NMR spectra, FT-IR spectra and Uv-visible spectra.Metal complexes of this ligand were synthesized by reaction of metal ions [Cr(III), Fe(II), Mn(II) and Zn(II)] with this ligand [L]. All metal complexes were characterized by elemental analysis, Magnetic susceptibility, electrical conduc- tance, Uv-vis spectra and FT-IR spectra. The antimicrobial activity of the ligand and its metal complexes were investigated for their (In-Vitro) antibacterial on (E. coli) and (Bacillusubtilis) and antifungal (A. niger) and (P. chrysogenum) activities. The result indicates that the growth of the tested organism was inhibited by the most of this complexes.
