Abstract: The title compound, C₁₇H₁₉N₄⁺·Br^-, is built up from 1,3-bis[(6-methyl-2-pyridinyl)methyl]imidazolium cations and bromide anions. Each of two 6-methyl-2-pyridyl rings is rotated out of the imidazole plane, making dihedral angles of 79.90 (9) and 86.40 (9)°. The packing is consolidated by aromatic - interactions between the pyridine rings of neighbouring molecules [centroid-centroid distance = 3.554 (2) Å] and by weak C-HN and C-HBr hydrogen bonds.
