Two novel alkynyl-protected silver-copper nanoclusters (Ph4P)2[Ag22Cu12(C≡CR)28] and (Ph4P)3[Ag42Cu12Cl(C≡CR)36] (Ag22Cu12 and Ag42Cu12Cl) were obtained by using a weak reducing agent diphenylsilane (Ph2SiH2). For the first time, a hybrid 55-atom two-shell Mackay icosahedron was found in Ag42Cu12Cl. The incorporation of a chloride in the metal icosahedron contributes to the stability of the cluster due to electronic and geometric factors.

具有混合麦凯二十面体 Ag42Cu12Cl 内核和八面体 Ag22Cu12 内核的炔基保护的双金属纳米团簇
两种新型炔基保护的银铜纳米团簇(Ph 4 P) 2 [Ag 22 Cu 12 (CQICR) 28 ] 和 (Ph 4 P) 3 [Ag 42 Cu 12 Cl(CQICR) 36 ] (Ag 22 Cu 12和Ag 42 Cu 12 Cl)通过使用弱还原剂二苯基硅烷(Ph 2 SiH 2 )获得。首次在Ag 42 Cu 12 Cl中发现杂化55原子双壳层麦凯二十面体。由于电子和几何因素，金属二十面体中氯化物的结合有助于团簇的稳定性。
