[GaBi3]（2-）与[Sm(C5Me4H)3]反应生成首个质子化三元金属间团簇[Sm@Ga(3-x)H(3-2x)Bi(10+x)](3-) （1; x = 0,1）。通过实验和量子化学相结合的方法阐明了在1的形成过程中Ga-H键的存在以及电子和质子的转移，从而合理化了溶剂乙烷-1,2-二胺作为Brønsted酸的作用。作为有机副产物，我们在（C5Me4H）（-）的C-C偶联中观察到以前未知的八甲基fulvene(2)。
Reaction of [GaBi3](2-) with [Sm(C5Me4H)3] yielded the first protonated ternary intermetalloid clusters [Sm@Ga(3-x)H(3-2x)Bi(10+x)](3-) (1; x = 0,1). The presence of the Ga-H bonds and the transfer of electrons and protons during the formation of 1 were elucidated by a combination of experimental and quantum chemical methods, thereby rationalizing the role of the solvent ethane-1,2-diamine as a Brønsted acid. As an organic by-product, we observed the previously unknown octamethylfulvene (2) upon C-C coupling of (C5Me4H)(-).
