摘要

摘要利用连续旋转模式下收集的电子衍射数据测定了标题化合物的晶体结构。在单斜空间群P21/c中，Z值为2，Z′值为0.5，成功地对该结构进行了运动学求解和细化。在晶体结构中，整个分子主要是扁平的。分子堆积呈现出人字形图案，与未氯化的类似物分子不同。晶体的最大面，面向支撑碳膜，被指定为（01‾1 \8254；$\bar｛1｝\bar{1｝$）。

Crystal structure of 9,10-bis-((perchloro-phenyl)-ethynyl)anthracene determined from three-dimensional electron diffraction data

Abstract The crystal structure of the title compound was determined using electron diffraction data collected in continuous rotation mode. The structure was successfully solved and refined kinematically in the monoclinic space group P21/c, with a Z value of 2 and Z′ value of 0.5. Within the crystal structure, the entire molecule is predominantly flat. The molecular packing exhibits a herringbone pattern, distinct from that of the unchlorinated analogue molecule. The largest facet of the crystals, which faces the supporting carbon film, is designated as (01‾1‾$\bar{1}\bar{1}$).

期刊介绍： Zeitschrift für Kristallographie – Crystalline Materials was founded in 1877 by Paul von Groth and is today one of the world’s oldest scientific journals. It offers a place for researchers to present results of their theoretical experimental crystallographic studies. The journal presents significant results on structures and on properties of organic/inorganic substances with crystalline character, periodically ordered, modulated or quasicrystalline on static and dynamic phenomena applying the various methods of diffraction, spectroscopy and microscopy.
