A triflate and alkynyl protected Ag(43) nanocluster with a passivated surface

A trifluoromethanesulfonate (OTf) and tert-butylacetylene ((t)BuC[triple bond, length as m-dash]C(−)) co-protected silver nanocluster (NC), Ag(43)((t)BuC[triple bond, length as m-dash]C)(24)(CF(3)SO(3))(8) (Ag(43)), was synthesized and characterized. Single crystal X-ray diffraction analysis reveale...

description A trifluoromethanesulfonate (OTf) and tert-butylacetylene ((t)BuC[triple bond, length as m-dash]C(−)) co-protected silver nanocluster (NC), Ag(43)((t)BuC[triple bond, length as m-dash]C)(24)(CF(3)SO(3))(8) (Ag(43)), 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@Ag(12)@Ag(30) structure. Both OTf and (t)BuC[triple bond, length as m-dash]C(−) ligands bonded with Ag atoms in a μ(3) mode. The application of Ag(43) as a catalyst for the reaction of silane with alcohol or H(2)O indicated that the surface ligands had a profound passivation effect, which significantly influenced the reactivity and selectivity.
