Abstract Triphenyllead derivatives Ph3PbL (HL = glycine, alanine, phenylalanine) and (Ph3Pb)2L′ (H2L′ = aspartic acid) have been prepared from Ph3PbOH and the appropriate amino acid. PH3Pb-leucinate has been synthesized from Ph3PbCl and Tl(I)-leucinate. From IR data structural proposals are inferred: Ph3Pb-glycinate is polymeric through monodentate carboxylate and coordinating NH2; Ph3Pb-alaninate, -phenylalaninate, and -leucinate contain bidentate carboxylate and non-coordinating NH2 groups and are probably monomeric. For (Ph3Pb)2-aspartate and (Me3Sn)2-aspartate a structure with coordinating NH2 and mono-and bidentate carboxylate groups is proposed.
