Abstract The complex Na[PtMe3(asp-N,αO,βO)] (H2asp = aspartic acid) was obtained as a solid from reaction of [PtMe3]2(SO4)·4H2O with aspartate. In D2O, the interchange between this complex with aspartate tridentate and [PtMe3(D2O)(asp-,αO)]t- was rapid on the NMR time-scale. Fac-[PtMe2Br(D2O)3]+ with D2asp at pD 2.5 gave the two isomers of [PtMe2Br(Dasp-N,αO)(D2O)] with the chelate ring trans to the methyl groups. With standing at pD 5-6, the two isomers of [PtMe2Br(asp-N,αO,βO)]- with N trans to methyl were formed, initially in similar proportions. With long standing, the isomer with N and β-carboxylate trans to methyl predominated. When the pD was decreased to 3, this isomer was in equilibrium with a complex in which water replaced β-carboxylate. UV irradiation of a solution containing the two isomers of [PtMe2Br(asp-N,αO,βO))]su- with N trans to methyl caused formation of the isomer with N trans to bromide.
