title: 3,3'-(Butane-1,4-di-yl)diimidazole-1,1'-diium bis-(triiodide).
abstract: The cations and anions of the salt, C(10)H(16)N(4) (2+)·2I(3) (-), are linked by N-H⋯I hydrogen bonds and π-π stacking inter-actions(with interplanar distances of 3.575 and 3.528 Å) into a three-dimensional supra-molecular network. The asymmetric unit contains two anions and two half-cations; each cation is centrosymmetric.
