Abstract: In the title compound, C₆H₁₄N₂²⁺·Cl₄I^-·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 Cl₄I^- 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-HCl hydrogen bonds.
