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 noncrystallographicC2symmetry. 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).
本文介绍了标题化合物 C17H11F5N4O,并将其与文献中两种密切相关的类似物进行了比较。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实体,呈现出明显的非结晶学 C2 对称性。这些二聚体又通过中等强度的 I 型 C-F...F-C 相互作用连接成拉长的四聚体。弱得多的 C-H...F 接触将四聚体连接成与 (101) 平行的宽二维亚结构。
