Bis(1-ethyl-3-methylimidazolium) Tetrachloropalladate(II)

The title compound, (C₆H₁₁N₂)₂[PdCl₄], is a salt that consists of a square-planar tetrachloropalladate(II) anion having interactions, via the chlorides, to ring H atoms on two 1-ethyl-3-methyl­imidazolium (MEI⁺) cations. The Pd atom resides at a center of inversion. Cl...H distances range from 2.75 to 3.24 Å, some of which suggest hydrogen bonding. As the title compound was obtained from an acidic room-temperature melt of the chloride salt of the MEI⁺ cation and AlCl₃, a possible use of this type of system as an alternate medium for crystallization is indicated.
