title: 1,3-Bis[(6-methyl-2-pyrid-yl)meth-yl]imidazolium bromide.
abstract: The title compound, C(17)H(19)N(4) (+)·Br(-), is built up from 1,3-bis-[(6-methyl-2-pyridin-yl)meth-yl]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 π-π inter-actions between the pyridine rings of neighbouring mol-ecules [centroid-centroid distance = 3.554 (2) Å] and by weak C-H⋯N and C-H⋯Br hydrogen bonds.
