Primary steps on the way towards Ga metal: The second structurally characterized gallium( I ) subhalide Ga 10 Br 10 (4‐ tert‐ butylpyridine) 10 (see picture, blue Ga, yellow N, green Br) allows an insight into the intra‐ and intermolecular redox process during the formation of α‐gallium by the disproportionation reaction of a metastable GaBr solution. During this process, metalloid clusters with an increasing number of “naked” Ga 0 atoms in the core and GaX 2 entities in the periphery grow.
