Synthesis, spectral characterisation, electrochemical, and fluorescence studies of biologically active novel Schiff base complexes derived from E-4-(2-hydroxy-3- methoxybenzlideneamino)-N-(pyrimidin-2-yl)benzenesulfonamide

The reasonable shifts in FT-IR and NMR spectral signals of the complexes with respect to the free ligand confirm good coordination of the Schiff-base ligand with the metal through imine nitrogen and oxygen atoms of Schiff base moiety. The Schiff-base ligand and the complexes were screened for antimicrobial activity and fluorescent behaviour. From the analytical and spectral data, the stoichiometry was found to be 1:2 for all the complexes. An octahedral structure was proposed. All the complexes were found to be active against bacteria and fungi.
