摘要

本文报道了1,1′，1”-[（2-溴-羟基）甲烷-三基]三苯C21H19BrO和1,1′，1”-[（2-碘-羟基）甲烷-三基]三苯C21H19IO的分子结构和合成。这两种化合物都是通过正己烷在单斜空间群P21/c中的缓慢蒸汽扩散从饱和THF溶液中结晶的。在1,1',1 " -[（2-碘-eth-氧）甲烷-三基]三苯的不对称单元中，两个独立的分子与其他分子没有密切接触，而在1,1',1 " -[（2-溴-eth-氧）甲烷-三基]三苯的结构中，分子之间通过C-H⋯π接触相互作用。

Synthesis and structure of 1,1′,1′′-[(2-bromoethoxy)methanetriyl]tribenzene and 1,1′,1′′-[(2-iodoethoxy)methanetriyl]tribenzene

Both compounds crystallized from a saturated solution in THF by slow vapour diffusion of n-hexane in the monoclinic space group P2₁/c. While the two independent molecules in the asymmetric unit of 1,1′,1′′-[(2-iodoethoxy)methanetriyl]tribenzene show no close contacts to other molecules, in the structure of 1,1′,1′′-[(2-bromoethoxy)methanetriyl]tribenzene the molecules interact with each other by C—H⋯π contacts.

The present study reports on the molecular structures and syntheses of 1,1′,1′′-[(2-bromoethoxy)methanetriyl]tribenzene, C₂₁H₁₉BrO, and 1,1′,1′′-[(2-iodoethoxy)methanetriyl]tribenzene, C₂₁H₁₉IO. Both compounds crystallized from a saturated solution in THF by slow vapour diffusion of n-hexane in the monoclinic space group P2₁/c. While the two independent molecules in the asymmetric unit of 1,1′,1′′-[(2-iodoethoxy)methanetriyl]tribenzene show no close contacts to other molecules, in the structure of 1,1′,1′′-[(2-bromoethoxy)methanetriyl]tribenzene the molecules interact with each other via C—H⋯π contacts.

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.
