A triflate and alkynyl protected Ag₄₃ nanocluster with a passivated surface.

ABSTRACT: A trifluoromethanesulfonate (OTf) and tert-butylacetylene ( ^t BuC[triple bond, length as m-dash]C^-) co-protected silver nanocluster (NC), Ag₄₃( ^t BuC[triple bond, length as m-dash]C)₂₄(CF₃SO₃)₈ (Ag₄₃), was synthesized and characterized. Single crystal X-ray diffraction analysis revealed its total structure. 43 Ag atoms are arranged into a three-concentric-shell Ag@Ag₁₂@Ag₃₀ structure. Both OTf and ^t BuC[triple bond, length as m-dash]C^- ligands bonded with Ag atoms in a μ₃ mode. The application of Ag₄₃ as a catalyst for the reaction of silane with alcohol or H₂O indicated that the surface l
