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-ICHNH)[GeI]} is composed of infinite inorganic layers that are formed by [GeI] octa-hedra connected in a corner-sharing manner with four equatorial I atoms. The organic (2-ICHNH) 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].
标题化合物是一种基于锗的混合金属卤化物，在光电应用中，它是比更常见的铅基类似物毒性更低的替代品。{(2-ICHNH)[GeI]} 由无限的无机层组成，这些无机层由 [GeI] 八面体构成，[GeI] 八面体通过与四个赤道面碘原子以角共享的方式相连。有机 (2-ICHNH) 阳离子交错排列在无机层之间。有两种类型的 2-碘代乙铵阳离子，具有顺叠和反叠构象。有机阳离子通过氢键和 I⋯I 接触与无机层相互作用。所研究的晶体通过围绕 [100] 轴旋转 180° 而形成孪晶。
