Abstract: The Hg atom in the title compound, (C₁₈H₁₈N₂)[HgCl_2.75I_1.25], is coordinated by four halogen atoms in a tetrahedral geometry. Two of the four halogen atoms are each disordered between I and Cl, with the I:Cl ratios being 0.5793 (15):0.4208 (15) and 0.6708 (15):0.3292 (15). The two independent cations lie on different inversion centres.
