摘要

硝基取代化合物6-[4-（1-环己基-1H-四唑-5-基）丁氧]-8-硝基-3,4-二氢喹啉-2(1H)- 1的组成已由单晶x射线衍射明确确定。本文还探讨了不同分子间相互作用在晶体填充中的作用。用x射线单晶衍射表征了6-[4-（1-环己基-1H-四唑-5-基）丁氧]-8-硝基-3,4-二氢喹啉-2(1H)- 1, C20H26N6O4 (I)的晶体结构。主要重点是确定硝基的位置，分子构象以及分子间相互作用对i的晶体堆积的作用。晶体结构主要由π -π， C - h⋯O, C - h⋯N, N⋯C（π）和O⋯C（π）相互作用巩固。利用Hirshfeld表面和指纹图谱进一步分析了不同相互作用对晶体堆积的贡献。

Crystal structure and Hirshfeld surface analysis of 6-[4-(1-cyclohexyl-1H-tetrazol-5-yl)butoxy]-8-nitro-3,4-dihydroquinolin-2(1H)-one

The composition of the nitro-substituted compound 6-[4-(1-cyclohexyl-1H-tetrazol-5-yl)butoxy]-8-nitro-3,4-dihydroquinolin-2(1H)-one has been unequivocally established from single-crystal X-ray diffraction. The molecular conformation and the role of the different intermolecular interactions in the crystal packing has also been explored.

The crystal structure of 6-[4-(1-cyclohexyl-1H-tetrazol-5-yl)butoxy]-8-nitro-3,4-dihydroquinolin-2(1H)-one, C₂₀H₂₆N₆O₄ (I), was characterized by single-crystal X-ray diffraction. The primary focus was to establish the position of the nitro group, the molecular conformation, and the role of intermolecular interactions towards the crystal packing of I. The crystalline structure is mainly consolidated by π–π, C—H⋯O, C—H⋯N, N⋯C(π) and O⋯C(π) interactions. The contributions of different interactions towards the crystal packing were further analyzed using Hirshfeld surface and fingerprint plots.
