title: 1,4-dimethyl-1,4-diazoniabicyclo[2.2.2]octane diiodide acetonitrile solvate.
abstract: In the crystal structure of the title compound, C(8)H(18)N(2)(2+).2I(-).CH(3)CN, the dication lies on a mirror plane containing the molecular dication threefold axis. The structure displays C-H...I interactions between H atoms of the 1,4-dimethyl-1,4-diazoniabicyclo[2.2.2]octane dication and the iodide anions. The H...I distances are in the range 2.96-3.18 (4) A. The dications pack forming channels along the b axis, which contain the iodide anions and acetonitrile solvent molecules.
