title: Ethyl-enediammonium dichloro-iodide chloride.
abstract: The asymmetric unit of the crystal structure of the title compound, C(2)H(10)N(2) (2+)·Cl(2)I(-)·Cl(-), contains two ethyl-ene-diammonium cations, two [ICl(2)](-) anions and two Cl(-) anions, of which one cation, one [ICl(2)](-) anion and one Cl(-) anion have site symmetry 2, with the mid-point of the C-C bond of the cation, the I atom of [ICl(2)](-) anion and the Cl(-) anion located on the twofold rotation axes. The two independent cations show different conformations, the N-C-C-N torsion angles being 160.1 (2) and -73.1 (4)°. The crystal structure is stabilized by extensive inter-molecular N-H⋯Cl hydrogen bonding.
