5-Nitro-1-(prop-2-en-1-yl)-1H-indazole

Abstract

In the crystal, the title molecule, C10H9N3O2, packs in layers approximately parallel to (100), which are formed by the association of zigzag chains constructed by weak C—H...O interactions. The allyl group is disordered over two positions, with a ratio of their occupancies close to 70:30.

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.…”
