1,4-Diazo­niabicyclo­[2.2.2]octane tetra­chloroiodate(III) chloride

In the title compound, C(6)H(14)N(2) (2+)·Cl(4)I(−)·Cl(−), the dication and the anions lie on special positions. The dication has mm2 symmetry with two bonded C atoms and the two N atoms located on a crystallographic mirror plane parallel to bc, and with a mirror plane parallel to ab passing through the mid points of the three C—C bonds. In the square-planar Cl(4)I(−) anion, two Cl atoms and the I atom are located on the mm2 axis; the other two Cl atoms are disordered over two postions of equal occupancy (0.25) across the mirror parallel to the ab plane. The Cl(−) anion is located on the mm2 axis. The crystal structure is stabilized by inter­molecular N—H⋯Cl hydrogen bonds.
