Abstract

New metal complexes of Ni(II), Zn(II) and Cu(II) with the Schiff base(2-((E)-2-hydroxy-5-((E)-m-tolyldiazenyl)-3-((E)-p-tolyldiazenyl)benzylidene)hydrazine-1-carbothioamide),(H2L) have been prepared and characterized by elemental and thermal analyses, FT-IR, UV–Vis, XRD analysis, SEM analysis, 1H-NMR, and C13 as well as conductivity and magnetic moments measurements. The IR spectra showed that the ligand acts as neutral bi-dentate ligand. The geometries of metal complexes were either octahedral or square pyramidal. The effect of the presence of an azo group on the biological activity of the ligand was investigated. The ligand and its complexes are biologically inactive due to the presence of azo-group.
