Abstract
Triorganotin and triorganolead derivatives of N-acetylglycine (AcGly), N-acetyl-α-alanine (AcAla), and N-acetylmethionine (AcMet), SnR3(AcGlyO)(R = Me, Bun, or Ph), PbR3(AcGlyO)(R = Me or Ph), SnR3(AcAlaO)(R = Me, Bun, or Ph), PbPh3(AcAlaO), SnR3(AcMetO)(R = Me or Ph), and PbPh3(AcMetO), have been prepared from MR3(OH)(R = Me or Ph) or (SnBUn 3)2O and the appropriate N-acetylamino-acid. According to i.r., Raman, and Mössbauer data the compounds are five-co-ordinate and polymeric in the solid state. The MR3 groups are co-ordinated by unidentate carboxylic groups and the oxygen of COamido. Co-ordination by NH groups is excluded. The compounds are essentially monomeric in solutions of CHCl3, C6H6, acetone, tetrahydrofuran, or pyridine. In dimethyl sulphoxide co-ordination occurs to form five-co-ordinate species.Keywords
