Abstract: In the title ionic compound, (C₈H₁₅N₂)₂[PdBr₄], the asymmetric unit consists of one square-planar [PdBr₄]^2- anion and two 1-n-butyl-3-methylimidazolium, [Bmim]⁺, cations, where the imidazolium rings are planar and the C atoms of the butyl substitutes are bent away from the ring planes at angles of 111.9 (3) and 112.3 (4)°. One methyl H atom and three ring H atoms of one of the two [Bmim]⁺ cations form C-HBr hydrogen bonds (2.81-2.92 Å and 157-165°), whereas the other cation is only involved in one hydrogen bond. Br atoms involved in hydrogen bonds are trans in the [PdBr₄]^2- ion.
