Abstract: The Hg atom in the title compound, (C₁₄H₁₈N₂)[HgBr₂I₂], is coordinated by four halogen atoms in a tetrahedral geometry. The four halogen atoms are disordered between I and Br, with the I:Br ratios being 0.824 (2):0.176 (2), 0.614 (2):0.386 (2), 0.325 (2):0.675 (2) and 0.237 (2):0.763 (2). The cation is disordered over two orientations and each was refined with an occupancy of 0.50.
