The polybromide salts [BrC(NMe 2 ) 2 ] 2 [Br 8 ] and [BrC(NMe 2 ) 2 ][Br 3 ] 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 [Br 8 ] 2– structure shows similarities to the very recently reported structure of the first octachloride [Cl 8 ] 2– .
