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

The crystal structure of 6-[4-(1-cyclo-hexyl-1<i>H</i>-tetra-zol-5-yl)but-oxy]-8-nitro-3,4-di-hydro-quinolin-2(1<i>H</i>)-one, C₂₀H₂₆N₆O₄ (<b>I</b>), was characterized by single-crystal X-ray diffraction. The primary focus was to establish the position of the nitro group, the mol-ecular conformation, and the role of inter-molecular inter-actions towards the crystal packing of <b>I</b>. The crystalline structure is mainly consolidated by π-π, C-H⋯O, C-H⋯N, N⋯C(π) and O⋯C(π) inter-actions. The contributions of different inter-actions towards the crystal packing were further analyzed using Hirshfeld surface and fingerprint plots.
