Abstract

Abstract. In this work, the synthesis and structural study by means of single-crystal X-ray diffraction of compounds of general formula Ch(C6H4CH2X)2 (Ch = O, S; X = Cl, Br, I) is reported. These compounds contain two flexible hydrocarbonated arms –CH2–X in the ortho positions to the Ch heteroatom. These compounds were synthesized through a linear synthesis starting from diphenylether or diphenylsulfide. Based on the structural analysis, we describe the more relevant molecular features as well as the non-covalent interactions that the heavy halogen atoms display with other moieties that promote the cohesion of the crystal arrangement. The Hirshfeld analysis displayed that the X···π, X···X, and C–H···X interactions are quite significant in the crystal arrangement.   Resumen.

二卤化合物 Ch(C6H4CH2X)2(Ch = O、S;X = Cl、Br、I)中的非共价相互作用。合成、晶体结构和 Hirshfeld 表面分析
摘要在这项工作中,报告了通式为 Ch(C6H4CH2X)2 (Ch = O、S;X = Cl、Br、I)的化合物的合成和通过单晶 X 射线衍射进行的结构研究。这些化合物在 Ch 杂原子的正交位置含有两个柔性烃化臂 -CH2-X。这些化合物是以二苯醚或二苯基硫醚为起点,通过线性合成法合成的。根据结构分析,我们描述了更多相关的分子特征以及重卤原子与其他分子之间的非共价相互作用,这些相互作用促进了晶体排列的内聚性。Hirshfeld 分析表明,X--π、X--X 和 C-H-X 相互作用在晶体排列中相当重要。摘要。在这项研究中,我们描述了几种具有一般 Ch(C6H4CH2X)2 (Ch = O, S; X = Cl, Br, I) 结构的化合物的单晶射线-X 衍射结构的研究,这几种化合物含有两个可弯曲的碳氢化合物-CH2-X,其位置与杂质 Ch 相同。这些化合物通过线性分析、二苯并二烯并二烯并二烯并二烯并二烯并二烯并二醚进行了精馏。通过结构分析,我们描述了最相关的分子特征,以及为使红色晶体具有内聚力而与其他功能组进行的非共价相互作用。对 Hirshfeld 表层的研究表明,X--π、X--X 和 C-H-X 相互作用与这种凝聚力密切相关。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
