Abstract

Anthranilic acid and benzaldehyde semicarbazone have the ability to form complexes with the metal ions, which were found to be important for various applications. In the present study, the attempts were carried to form complexes of anthranilic acid and benzaldehyde semicarbazone as ligands with Cobalt chloride (CoCl2. 6H2O), Nickel chloride NiCl2. 6H2O and Copper chloride (CuCl2. 5H2O), in the molar ratio 1:1:1. The resulting complexes have been characterized on the basis of elemental analysis, magnetic measurement, IR and UV spectral analysis, conductivity measurement, thermal analysis, antimicrobial activities. Analysis of results reviles that the complexes shows octahedral geometry, electrolytic nature and having more antimicrobial activity than the ligands. The ligands are bonded through oxygen and nitrogen.

Keywords: Anthranilic acid, benzaldehyde, semicarbazone oxygen and nitrogen.
