摘要

标题化合物是一种基于锗的杂化金属卤化物，代表了在光电应用中更流行的基于铅的类似物的毒性更低的替代品。{(2- ic2h4nh3)2[GeI4]} n是由[GeI6]4-八面体与四个赤道I原子以共享角的方式连接而成的无限无机层组成的。有机(2-IC2H4NH3)+阳离子在无机层间穿插。2-碘乙基铵阳离子有向斜构象和反平面构象两种。有机阳离子通过氢键和I⋯I接触与无机层相互作用。所研究的晶体在[100]周围旋转180°而成双晶。

Crystal structure and Hirshfeld surface analysis of the layered hybrid metal halide poly[bis(2-iodoethylammonium) [di-μ-iodido-diiodidogermanate(II)]]

The crystal structure of the title compound contains infinite inorganic two-dimensional layers formed by [GeI₆]⁴⁻ octahedra. These layers are interleaved with the organic 2-iodoethylammonium cations.

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-IC₂H₄NH₃)₂[GeI₄]}_n is composed of infinite inorganic layers that are formed by [GeI₆]⁴⁻ octahedra connected in a corner-sharing manner with four equatorial I atoms. The organic (2-IC₂H₄NH₃)⁺ cations interleave the inorganic layers. There are two types of 2-iodoethylammonium cations, with synclinal and antiperiplanar conformations. The organic cations interact with the inorganic layers through hydrogen bonds and I⋯I contacts. The crystal under investigation was twinned by a 180° rotation around [100].

期刊介绍： Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
