A novel alkynyl-stabilized silver-copper alloy nanocluster with the composition of AgCu(BuCHCC)(PPh) was prepared by the (PPh)CuBH-mediated reduction approach. The nanocluster features a centred disordered-octahedral AgCu 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.
通过 (PPh)CuBH 介导的还原方法，制备了具有组成 AgCu(BuCHCC)(PPh) 的新型炔基稳定的银铜合金纳米团簇。该纳米团簇具有以无序八面体 AgCu 核为中心的特征，该核由混合炔基和三苯基膦配体保护。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方面起着重要作用。标题簇在 4-硝基苯酚的催化加氢中表现出优异的性能，表明基于团簇的催化剂具有光明的未来。
