The polybromide salts [BrC(NMe₂)₂)]₂[Br₈] and [BrC(NMe₂)₂)][Br₃]were synthesized in the ionic liquid [BMP][OTf] (1‐butyl‐1‐methyl‐pyrrolidinium triflate). The compounds were characterized by Raman, NMR, and X‐ray single crystal structure determination as well as quantum‐chemical calculations. The polybromide dianion [Br₈]²⁻ structure shows similarities to the very recently reported structure of the first octachloride [Cl₈]²⁻.
