Bis(2-ethyl-1H-imidazol-3-ium) tetra­chloridomercurate(II)

The crystal structure of the title compound, (C(5)H(9)N(2))(2)[HgCl(4)], consists of discrete tetra­chloridomercurate dications and discrete 2-methyl­imidazolium cations. In the complex anion, the mercury cations are coordinated by four chloride anions with distances between 2.4568 (14) and 2.4936 (15) Å in a tetra­hedral geometry. In the crystal, the cations and anions are connected by inter­molecular N—H⋯Cl inter­actions. One C atom of the cations is disordered and was refined using a split model (occupancy ratio 0.75:0.25).
