The syntheses and properties of two bimetallic nanoclusters [Au₄Ag₂₃(C≡CtBu)₁₀(dppf)₄Cl₇](PF₆)₂ and [Au₅Ag₂₄(C≡CC₆H₄‐p‐tBu)₁₆(dppf)₄Cl₄](PF₆)₃ are reported. The Au atoms distributed in both the cores and the surface motifs are clearly determined. The two nanoclusters show distinctly different geometric structures and electronic properties, which are attributed to the subtle changes in the surface alkynyl structures.

合金纳米簇Au4Ag23和Au5Ag24中配体控制的掺杂效应

的合成和两个双金属纳米簇的性质[金₄银₂₃（C≡C吨卜）₁₀（DPPF）₄氯₇ ]（PF ₆）₂和[金₅银₂₄（C≡CC ₆ ħ ₄ - p -吨Bu）₁₆（dppf）₄ Cl ₄ ]（PF ₆）₃被报道。清楚地确定了分布在核和表面基序中的金原子。这两个纳米簇显示出明显不同的几何结构和电子性质，这归因于表面炔基结构的细微变化。
