Abstract

New diorganotin(IV) complexes of the type Ph2SnL2, Bu2SnL2 and Me2SnL2 of the ligand 2-[(phenylcarbonyl)amino]propanoic acid (HL) ligand formed by reaction of benzoyl chloride with alanine in presence of sodium hydroxide. The prepared complexes were characterized by infrared, nuclear magnetic resonance (1H, 13C, 119Sn NMR) spectral data and elemental analysis and conductance measurements. From the spectral measurements, monomer structures for the complexes were proposed. Bidentate and Octahedral geometry was proposed for the complexes prepared. Bioassay result 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 show a higher inhibition percentage then diorganotin carboxylate.
