Abstract

New diorganotin(IV) complexes of the type Ph2SnL2, Bu2SnL2 and Me2SnL2 of the ligand benzamidophenylalanine (LH). Ligand formed by reaction of benzoyl chloride with phenylalanine in presence of sodium hydroxide. The prepared complexes were characterized by elemental analysis, infrared, conductance measurements and nuclear magnetic resonance (1H, 13C and 119Sn NMR) spectral data. From the spectral measurements, monomer structures, 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 show a higher inhibition percentage then diorganotin carboxylate.
