Abstract

Triphenyltin(IV) complexes of N-acetylglycine, N-acetyl-L-leucine, N- acetyl-L-asparagine and N-acetyl-L-tyrosine were prepared by two methods and characterized by means of different spectroscopic methods (FTIR, multinuclear, 1H, 13C and 119Sn NMR and 119Sn Mossbauer). The spectroscopic data indicated that the N-acetylglycine complex adopts a trigonal-bipyramidal structure in which the monodentate carboxylate and the amide -C=O group are bound to the same organotin(IV) moiety. The other three complexes are linear oligomers in which the planar Ph3Sn(IV) is coordinated axially by a monodentate carboxylate and an amide -C=O from two different ligands. At the C-terminal end of the oligomer chain there is a tetracoordinated tin(IV) with a monodentate carboxylate as donor group.
