title: 3,3'-Dimethyl-1,1'-methyl-ene-diimidazolium dibromide.
abstract: In the crystal structure of the title compound, C(9)H(14)N(4) (2+)·2Br(-), the cation and anions have crystallographic mirror symmetry, with the mirror plane running through the central CH(2) group for the cation. The latter are stacked along the a axis, forming channels hosting the bromide anions. The crystal packing is stabilized by C-H⋯Br hydrogen-bonding inter-actions, generating a two-dimensional network.
