Abstract :

New Schiff base has been prepared from 2–sulphanilamidothiazole and 2–hydroxy–3–methoxy benzaldehyde in ethanolic media and then complexed with Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) ions. The synthesized ligand and complexes were characterised by Elemental analysis, Molar conductance ,Magnetic susceptibility, IR, UV, 1H & 13C NMR, EPR and Fluorescence studies.The spectral data of the complexes have revealed bidentate complexing nature of the Schiff base ligand through phenolic oxygen and azomethine nitrogen atoms. The Schiff base ligand and the complexes were screened for antimicrobial activity and fluorescent behaviour. From the analytical and spectral data, the stoichiometry has been found to be 1:2 for all the complexes. An octahedral structure has been proposed. All the new complexes were found to be active against bacteria and fungi.
