A novel alkynyl-stabilized silver–copper alloy nanocluster with the composition of [Ag13−xCu6+x(tBuC6H4C![[triple bond, length as m-dash]](https://www.rsc.org/images/entities/char_e002.gif)
C)14(PPh3)6](SbF6)3 was prepared by the (PPh3)2CuBH4-mediated reduction approach. The nanocluster features a centred disordered-octahedral Ag7Cu6 kernel, which is protected by hybrid alkynyl and triphenylphosphine ligands. Structural comparison of this two-electron nanocluster with other alkynyl-capped Ag/Cu ones suggested that the structure of alkynyl ligands played an important role in dictating the structures of the resulting nanoclusters. The title cluster showed high performance in the catalytic hydrogenation of 4-nitrophenol, indicative of the bright future of cluster-based catalysts.

用于催化氢化的炔基保护的 Ag13−xCu6+x 纳米团簇
通过( PPh _ _ _ _ _ _ _ _ _ _ __ _ _ _ _ _ _ _ _ _ 3 ) 2 CuBH 4介导还原法。纳米团簇具有中心无序八面体 Ag 7 Cu 6核，其受到混合炔基和三苯基膦配体的保护。这种双电子纳米团簇与其他炔基封端的 Ag/Cu 纳米团簇的结构比较表明，炔基配体的结构在决定所得纳米团簇的结构中起着重要作用。标题簇在4-硝基苯酚的催化加氢中表现出高性能，预示着簇基催化剂的光明前景。
