Crystal structure and Hirshfeld surface analysis of the layered hybrid metal halide poly[bis(2-iodoethylammonium) [di-μ-iodido-diiodidogermanate(II)]]
The title compound is a germanium-based hybrid metal halide that represents a less-toxic alternative to more popular lead-based analogues in optoelectronic applications. {(2-IC<sub>2</sub>H<sub>4</sub>NH<sub>3</sub>)<sub>2</sub>[GeI<sub>4</sub>]} <sub><i>n</i></sub> is composed of infinite inorganic layers that are formed by [GeI<sub>6</sub>]<sup>4-</sup> octa-hedra connected in a corner-sharing manner with four equatorial I atoms. The organic (2-IC<sub>2</sub>H<sub>4</sub>NH<sub>3</sub>)<sup>+</sup> cations inter-leave the inorganic layers. There are two types of 2-iodo-ethyl-ammonium cations, with synclinal and anti-periplanar conformations. The organic cations inter-act with the inorganic layers through hydrogen bonds and I⋯I contacts. The crystal under investigation was twinned by a 180° rotation around [100].
