In this work novel organic based compound sulphonamide phenyl hydrazone derivatives and their thermal and biological activities were investigated. A new series of sulphonamide phenyl hydrazone containing ligand and their Mn(III) based heterochelate were synthesized by various acyl chloride. The structure of sulphonamide phenyl hydrazone ligands were confirmed by 1H NMR, IR, Elemental analysis and their heterochelates were confirmed by thermal studies (TGA/DTG & DSC) and FAB Mass spectroscopy. All the synthesized compounds were screened for their In-Vitro biological study against Gram+ve (Bacillus megaterium) and Gram-ve (E.coli) microorganism. The results confirmed that sulphonamide phenyl hydrazone based heterochelates have a great potential and significant for further investigation.
