Rational construction of a library of M₂₉ nanoclusters from monometallic to tetrametallic.

ABSTRACT: Exploring intermetallic synergy has allowed a series of alloy nanoparticles with prominent chemical-physical properties to be produced. However, precise alloying based on a maintained template has long been a challenging pursuit, and little has been achieved for manipulation at the atomic level. Here, a nanosystem based on M₂₉(S-Adm)₁₈(PPh₃)₄ (where S-Adm is the adamantane mercaptan and M is Ag/Cu/Au/Pt/Pd) has been established, which leads to the atomically precise operation on each site in this M₂₉ template. Specifically, a library of 21 species of nanoclusters ranging from monometallic to tetrametallic constitutions has been successfully prepared step by step with in situ synthesis, target metal-exchange, and forced metal-exchange m
