title: 3,3'-Dimethyl-1,1'-ethyl-ene-diimidazolium dibromide.
abstract: The title compound, C(10)H(16)Br(2)N(4), was synthesized by the reaction of 1-methyl-imidazole and 1,2-dibromo-ethane in toluene. The complete dication is generated by a crystallographic inversion centre situated at the mid-point of the ethane C-C bond. In the crystal structure, weak inter-molecular C-H⋯Br inter-actions link the mol-ecules into chains along the b axis and an intramolecular C-H⋯Br close contact is also present.
