Synthesis and Spectroscopic Studies (Mössbauer, IR and NMR) of Biologically Active Organotin(IV) Complexes of Schiff Bases Derived from 2-Amino-5-phenyl-1,3,4-oxadiazole

Abstract

A few new organotin(IV) complexes of tridentate donor Schiff bases of salicylaldehyde, 4-hydroxybenzaldehyde, 2-hydroxyacetophenone, 4-hydroxyaceto-phenone with 2-amino-5-phenyl-1,3,4-oxadiazole have been synthesised and characterised by elemental analyses. ¹H NMR, UV, IR and Mössbauer spectroscopic studies show hexa-coordination about the tin atom which is arranged in a distorted octahedral geometry. Representative complexes have been screened for their fungicidal as well as bactericidal activity and found to be quite active.
