ABSTRACT:

4-(methylsulfanyl)-2-[(phenylcarbonyl)amino]butanoic acid have been synthesized by the reaction of benzoyl chloride with 2-amino-4-(methylsulfanyl)butanoic acid in the presence of sodium hydroxide. Triorganogermanium(IV) complexes of the type Ph3GeL, Bu3GeL and Me3GeL (where L = 4-(methylsulfanyl)-2-[(phenylcarbonyl)amino]butanoic acid were also synthesized. The prepared ligand and organometallic complexes were characterized by elemental analysis, infrared and nuclear magnetic resonance (1H and 13C) spectral data. Spectral data showed that the ligand coordination through the oxygen atom of the deprotonated hydroxyl group. Monodentate, tetrahedral geometry were proposed for the complexes.
