1-(5-Nitro-1H-indazol-1-yl)ethanone

Abstract

In the title compound, C9H7N3O3, paired ribbons of molecules running in thea-axis direction are formed by intermolecular C—H...O and offset π-stacking interactions.

Crystal structure and Hirshfeld surface analysis of 5-[(5-nitro-1H-indazol-1-yl)methyl]-3-phenyl-4,5-dihydroisoxazole

“…In the title compound, the corresponding bond lengths are 1.229 (2), 1.238 (1) and 1.457 (2) Å , respectively. The C aromatic -bound nitro group and indazole ring are inclined to each other by a dihedral angle of 4.0 (2) in AKEFIH (Boulhaoua, El Hafi et al, 2016b), 7.0 (9) in APALOU (Boulhaoua, Essaghouani et al, 2016), 4.6 (4) in KEHTEZ (Boulhaoua et al, 2017), 19.2 (2) in PUVSOO (Zaleski et al, 1998), 1.9 (9) in UJUJOA (Boulhaoua, El Hafi et al, 2016a) and 7.9 (5) in UJUKOB (Boulhaoua, Abdelahi et al, 2016), compared to 6.5 (6) in the title compound. Therefore, the various geometrical parameters for the title compound are typical for 1-methyl-5-nitro-1H-indazoles.…”
