The asymmetric unit of the title compound, (C7H10N)2[HgBr4], consists of one cation and one half-anion, bisected by a twofold rotation axis passing through the metal atom. The anion exhibits a distorted tetrahedral arrangement about the HgII atom. In the crystal, the cations and anions are linked by N-HBr hydrogen-bonding interactions along . Cation-cation - stacking and BrBr intermolecular interactions are absent.
