Abstract

The title compound, C17H11F5N4O, is described and compared with two closely related analogues in the literature. There are two independent molecules in the asymmetric unit, linked by N-H···O hydrogen bonds and π-π interactions into dimeric entities, presenting a noticeable noncrystallographic C2 symmetry. These dimers are in turn linked by a medium-strength type-I C-F···F-C interaction into elongated tetramers. Much weaker C-H···F contacts link the tetramers into broad two-dimensional substructures parallel to (101).

在(Z)-3-甲基-4-[2-(4-甲基苯基)肼基]-1-(五氟苯基)- 1h -吡唑-5(4H)- 1中由i型- C-F···F-C连接的二聚体。

对标题化合物c17h11f5n40o进行了描述，并与文献中两个密切相关的类似物进行了比较。在不对称单元中有两个独立的分子，通过N-H···O氢键和π-π相互作用连接成二聚体，呈现出明显的非晶体C2对称。这些二聚体依次通过中等强度的i型C-F···F-C相互作用连接成细长的四聚体。更弱的C-H··F接触将四聚体连接成平行于(101)的宽二维亚结构。

期刊介绍： Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
