Abstract

A NSO tridentate Schiff base ligand (E)-2-(5-bromo-2-hydroxy-3-methoxybenzylidene)-N-ethyledrazine-1-carbothioamide (L1) of a new carbothioamide has been synthesized. Co2+ and Ni2+ metal was introduced to tridentate Schiff base ligand to make coordination complexes. Square planar complex of Ni2+ and octahedral complex of Co2+ metal-ions were formed respectively and compounds Na [NiLCl] and Na [CoL(OH2)2Cl] have been found under basic condition. Characterization of these compounds are done by on the basis of melting point, FT-IR spectroscopy and UV-Visible spectroscopy. As the new complexes possesses azomethine(=C=N−) group so they have potential biological activity. For antibacterial study the solution of complexes and ligand was applied against the bacteria S. aureus and B. subtilis to find out their inhibition with bacteria.

Keywords: Thiosemicarbazone; Schiff Base Ligand; Cobalt Complex; Nickel Complex; FT-IR Spectroscopy; UV-Visible Spectroscopy
