In the title compound, (C8H12N)2[ZnBr4], the coordination geometry of the anion is approximately tetrahedral. The Zn-Br bond lengths range from 2.3901 (19) to 2.449 (2) Å and the Br-Zn-Br angles range from 107.09 (8) to 112.48 (8)°. In the crystal, each [ZnBr4]2- anion is connected to four cations through two N-HBr and two C-HBr hydrogen bonds, forming two-dimensional (cation)2anion(cation2) sheets parallel to the bc plane. Within each sheet, the anions are arranged in stacks with no significant inter-anion BrBr interactions [the shortest being > 4.3 Å], while the cations are in chains, with weak - stacking interactions [centroid-centroid distance = 3.991 Å] between cations interacting with the same anion.
