Site-specific doping of silver atoms into a Au₂₅ nanocluster as directed by ligand binding preferences.

ABSTRACT: For the first time site-specific doping of silver into a spherical Au₂₅ nanocluster has been achieved in [Au₁₉Ag₆(MeOPhS)₁₇(PPh₃)₆] (BF₄)₂ (Au₁₉Ag₆) through a dual-ligand coordination strategy. Single crystal X-ray structural analysis shows that the cluster has a distorted centered icosahedral Au@Au₆Ag₆ core of D ₃ symmetry, in contrast to the I _h Au@Au₁₂ kernel in the well-known [Au₂₅(SR)₁₈]^- (R = CH₂CH₂Ph). An interesting feature is the coexistence of [Au₂(SPhOMe)₃] dimeric staples and [P-Au-SPhOMe] semi-staples in the title cluster, du
