The mechanism of metal exchange in non-metallic nanoclusters

We substituted gold atoms in fcc structured Au(28) and Au(36) nanoclusters with a Ag(i)SR complex and obtained Ag(x)Au(28−x) and Ag(x)Au(36−x) nanoclusters, respectively. The positive electrostatic potential (ESP) and dual descriptor (Δf) values were calculated for the metal cores of both nanocluste...

Descripción
Sumario:We substituted gold atoms in fcc structured Au(28) and Au(36) nanoclusters with a Ag(i)SR complex and obtained Ag(x)Au(28−x) and Ag(x)Au(36−x) nanoclusters, respectively. The positive electrostatic potential (ESP) and dual descriptor (Δf) values were calculated for the metal cores of both nanoclusters, which indicated that the metal exchange is an electrophilic reaction.
