Triorganotin(IV) derivatives of N-acetyl-l-phenylalanine (HAA) and N-acetyl-l-phenylalanylglycine (HDP), R3SnAA and R3SnDP (where R = methyl, n-propyl, n-butyl, phenyl and cyclohexyl, respectively), have been prepared from triorganotin(IV) chlorides (R3SnCl) and the sodium salt of the appropriate N-acetylamino acids. All the compounds in the solid state have a polymeric structure with a unidentate
