Some new coordination compounds of tin(II) have been synthesized by the reaction of tin(II) methoxide with the Schiff bases prepared by condensation of aldehyde/ketones with sulpha drugs. These complexes have been characterized on the basis of elemental analysis, ultraviolet, infrared, 1H NMR and 119Sn NMR spectral studies. The analytical data of complexes indicate 1:2 metal ligand stoichiometry of the type of [ML2], where M = Sn(II). The ligands be haved as bidentate chelating agents and bonded to the metal ion through imines nitrogen and ox ygen atom of either moiety of ligand. The antibacterial activities of the ligands and their tin(II) coordination compounds have been screened in vitro against the o ga ism Escherichia coli, Staphylococus aureus, Prouteus mirabilis,and Bacillus thurengiensis.
