Three phosphine ligand-protected monodisperse [Au13(Dppm)6](BPh4)3, [Au18(Dppm)6Br4](BPh4)2, and [Au20(Dppm)6(CN)6] nanoclusters are successfully obtained by thiol destroy and size focusing method. Meanwhile, [Au18(Dppm)6Br4](BPh4)2 could be converted into [Au13(Dppm)6](BPh4)3 and [Au20(Dppm)6(CN)6] by engineering the surface ligands under PPh3 or NaBH3CN, respectively. Further, the [Au18−xAgx(Dppm)6Br4](BPh4)2 can be synthesized by target metal exchange of [Au18(Dppm)6Br4](BPh4)2 with AdmS-Ag. The work will contribute to more intensive understanding on synthesizing phosphine-protected nanoclusters and structure transformation by ligand/metal engineering.
