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

The title compound, (C6H11N2)(2)[PdCl4], is a salt that consists of a squar e-planar tetrachloropalladate(II) anion having interactions, via the chlori des, 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 Angstrom , 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.
