diorganotin(IV), 2-thioacetic-5-phenyl-1, 3, 4-oxadiazole, fungicidal activity


Complexes of the type R2SnL2, where R = phenyl, butyl and methyl and LH = 2-thioacetic-5-phenyl-1,3,4-oxadiazole, have been synthesized and characterized by physico-chemical (elemental analysis, and electrolytic conductance) and spectral (UV-Visible, IR and (1H, 13C and 119Sn NMR) techniques. Monomer structures for the complexes, bidentate and octahedral geometry was proposed for the complexes prepared. Preliminary in vitro tests for fungicidal activity show that all prepared compounds display good activity to Gibberela, Cercospora arachidicola, Physolospora piricola and Fusarium oxysporum. Moreover, the Ph2SnL2 shows a higher inhibition percentage then diorganotin carboxylate.
