Abstract: The Hg atom in the title compound, (C₁₂H₁₄N₂)[HgBr₂Cl₂], is coordinated by four halogen atoms in a tetrahedral geometry. The cation lies on a centre of inversion and the anion about a mirror plane. The two halogen atoms on the mirror plane are disordered between Br and Cl in ratios of 0.921 (4):0.079 (4) and 0.795 (4):0.205 (4). The halogen atom in the general position is disordered between Br and Cl in a ratio of 0.142 (1):0.858 (1).
