Synthesis, Characterization and Antibacterial Activity of some New Metal Complexes Containing Semicarbazide

Abstract

The research includes the preparation and characterization of the new N-cyclohexyl-2-((dimethylcarbamoyl) carbamothioyl) hydrazine-1-carboxamide (L). Metal ions Co+2, Ni+2, and Cu+2 were combined with the ligand (L) to form three transition metal complexes. The chemical formulas are the following [LCoCl2.H2O)], [LNiCl2H2O], [LCuCl2.H2O]. The reaction was performed by mixing metal ligand in a [1:1] mole ratio using (MeOH) acting as a solvent. The entity of the expected structure of the ligand and its metal complexes were illustrated through a range of physicochemical techniques. These include: FT-IR, electronic spectra, (1H and 13C-NMR) spectra, elemental analysis(CHNS), chloride content, metal content, melting point, molar conductivity, and magnetic susceptibility of three coordinate complexes with deformed octahedral geometry around the center atom was determined by the spectral and analytical for the Co+2, Ni+2 and Cu+2 atoms. The biological activity (anti bacterial) (G+) and (G-) bacterial was explored
