The bromine‐rich bromidoplatinates(IV) [NBu3Me]2[Pt2Br10](Br2)2 (1) and [NBu3Me]2[Pt2Br10](Br2)3 (2) were prepared by reaction of PtBr4 and elemental bromine in the ionic liquid [MeBu3N][N(Tf)2] [N(Tf)2 = bis(trifluoromethylsulfonyl)amide]. Both bromine‐rich bromidoplatinates(IV) contain [Pt2Br10]2– anions and [NBu3Me]+ cations as voluminous building units with an almost identical structural arrangement and very similar unit cells. The difference of the title compounds is related to the specific number of Br2 molecules that link the [Pt2Br10]2– anions to three‐dimensional networks. Whereas 1 is relatively stable under inert conditions, 2 releases bromine even at ambient pressure. The title compounds are characterized by single‐crystal structure analysis and Raman spectroscopy.
