Crystal structure and Hirshfeld surface analysis of the salt 2-iodoethylammonium iodide – a possible side product upon synthesis of hybrid perovskites
The title organic-inorganic hybrid salt, C<sub>2</sub>H<sub>7</sub>IN<sup>+</sup>·I<sup>-</sup>, is isotypic with its bromine analog, C<sub>2</sub>H<sub>7</sub>BrN<sup>+</sup>·Br<sup>-</sup> [Semenikhin <i>et al.</i> (2024 ▸). <i>Acta Cryst.</i> E<b>80</b>, 738-741]. Its asymmetric unit consists of one 2-iodo-ethyl-ammonium cation and one iodide anion. The NH<sub>3</sub> <sup>+</sup> group of the organic cation forms weak hydrogen bonds with four neighboring iodide anions, leading to the formation of supra-molecular layers propagating parallel to the <i>bc</i> plane. Hirshfeld surface analysis reveals that the most important contribution to the crystal packing is from N-H⋯I inter-actions (63.8%). The crystal under investigation was twinned by a 180° rotation around [001].
