Abstract Reaction of [GaBi 3 ] 2− with [Sm(C 5 Me 4 H) 3 ] yielded the first protonated ternary intermetalloid clusters [Sm@Ga 3− x H 3−2 x Bi 10+ x ] 3− ( 1 ; x =0,1). The presence of the GaH 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 CC coupling of (C 5 Me 4 H) − .
