Abstract
A bidentate Schiff base ligand having nitrogen sulphur donor atoms was derived from the condensation of S-benzyldithiocarbazate (SBDTC) with cinnamaldehyde. The ligand was then chelated with Co(II) and Sb(III). Molecular structures of the Schiff base ligand and its complexes were established through elemental analysis, conductivity and magnetic susceptibility measurements as well as spectroscopic data (FT-IR, UV-Vis and ESI-MS). The geometrical structures are tetrahedral and octahedral for the cobalt complex and antimony complex respectively. The biological activities of the ligand and its complexes were investigated against the gram-positive and gram-negative bacteria and the fungus strain. The metal complexes were shown to possess more.
Keywords: Schiff base, metal complex, antibacterial activity, antifungal activity.
