Abstract

Author(s): Jagadish Tota and Satyanarayana Battu*

Novel Metal (II) complexes derived from 2-benzothiazolamine and imidazole-2-carboxaldehyde were synthesized. These compounds were characterised by FT-IR, Elemental analysis, Mass, 1H NMR, TGA, Molar conductance, Electronic spectra, Magnetic moment measurements and SEM. The analytical data has shown the metal to ligand ratio is 1:1. IR spectral studies revealed that binding sites of ligand with metal ions through the azomethine nitrogen and imidazole nitrogen atoms. Thermal analysis confirms there are no coordinated water molecules present in the metal complexes. Schiff base and its metal complexes were screened against the bacterial strains such as gram positive and gram negative and fungal strain aspergillus niger to know the anti microbial activity of these compounds, in which metal complexes have shown greater activity than free ligand.
