Synthesis, Characterization and Antibacterial Activity of Sn(II) and Sn(IV) Ions Complexes Containing N-Alkyl-N-Phenyl Dithiocarbamate Ligands

Abstract

In the current study, ligands S2 donor atoms, sodium N-methyl-N-phenyldithiocarbamate [L1], and sodium N-ethyl-N-phenyldithiocarbamate [L2] are prepared from carbon disulfide with N-methyl aniline and N-ethyl aniline, respectively. Sn(II) and Sn(IV) ions complexes containing N-alkyl-N-Phenyl dithiocarbamateare prepared and characterized by CHNS elemental analysis, infrared spectroscopy (FT-IR), 1HNMR-spectroscopy, mass spectroscopy, UV-visible spectroscopy, magnetic susceptibility and conductivity measurements. The analytical and spectral data show that the stoichiometry for all complexes is 1 : 2 metal to ligand. The spectral data confirm good coordination of dithiocarbamate ligand with the metal through sulfur atoms of dithiocarbamate moiety. Molar conductivity of complexes are measured using DMF as a solvent and indicated that the complexes of Sn(II) are non-ionic whereas Sn(IV) complexes are ionic. The ligands L1 and L2 and their complexes are examined against Staphylococcus aureus bacteria and Escherichia coli bacteria.
