"New Ligand a Type of Schiff Bases Derived from" 2- Mercaptobenzothizole and Its "Complexes with Some Metal Ions": Preparation, Characterization, and Evaluation of Biological Activity

Abstract

In this study, a new Schiff base compound was synthesized and identified as a ligand (LH). A phenyl ketone with the molecular formula (C48H35N5O2S) -2-(2-(4-(1-(4'-("benzothiazole-2-ylamino)-[1, 1'-biphenyl]-4-yl) imino) ethyl) phenyl) imino)-1,2-diphenylethylidene) amino) benzoic acid . In order to generate complexes with metal ions pd (II), Hg(II), Co(II), and Ni(II), a newly synthesised ligand called LH was used. In addition, metal salts was utilised in order to react with a ligand. In all, there were four stages involved in the synthesis of ligand (LH). The product had a 79.85% yield and 100-102°C melting point. In order to determine the identities of ligands and the complexes they form, analytical techniques such as the FT-IR, UV-Vis, melting points, molar conductivity, CHN atomic absorption, magnetic sensitivity, XRD, and FESEM have been used. An investigation of the biological activity of Ligand and its complexes revealed that both were successful in inhibiting the growth of the bacteria under study.
