AbstractSynthesis and characterization of some novel di and tri‐benzyl tin(IV) complexes of some Schiff bases are reported. The1H‐NMR,13C‐NMR,119Sn‐NMR, IR, Elemental Analysis and119Sn Mössauber studies are made for structural determination. Spectroscopic data reveals that the ligand molecule is bound to the tin atom through oxygen. On the basis of spectroscopic data tetrahedral geometry is proposed for the synthesized compounds. The synthesized compounds have been tested against various microorganisms. The results obtained show that the synthesized compounds have promising activity against all the tested micro
