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 indazole portion is planar and the nitro group and the pendant phenyl ring are coplanar within 7°. Oblique stacks along the a-axis direction are formed by π–π-stacking inter­actions between the indazole unit and the pendant phenyl rings of adjacent mol­ecules. The stacks are linked into pairs through C—H⋯O hydrogen bonds.

Abstract

In the title compound, C₁₇H₁₄N₄O₃, the indazole unit is planar to within 0.0171 (10) Å and makes dihedral angles of 6.50 (6) and 6.79 (4)°, respectively, with the nitro and pendant phenyl groups. The conformation of the oxazole ring is best described as an envelope. In the crystal, oblique stacks along the a-axis direction are formed by π–π stacking inter­actions between the indazole unit and the pendant phenyl rings of adjacent mol­ecules. The stacks are linked into pairs through C—H⋯O hydrogen bonds. Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H⋯H (36.3%), O⋯H/H⋯O (23.4%), C⋯H/H⋯C (13.4%) and N⋯H/H⋯N (11.4%) inter­actions.

Chemical context  

Indazole derivatives are of pharmaceutical inter­est in a variety of therapeutic areas. They exhibit a variety of biological activities such as HIV protease inhibition (Patel et al., 1999 ▸), anti­arrhythmic and analgesic activities (Mosti et al., 2000 ▸), and anti­tumor activity and anti­hypertensive properties (Bouissane et al., 2006 ▸; Abbassi et al., 2012 ▸). The present work is a continuation of an investigation of indazole derivatives published by our team (Boulhaoua et al., 2015 ▸). In this context, we synthesized the title compound by reaction of benzaldoxime with 1-allyl-5-nitro-1H-indazole in a biphasic medium (water–chloro­form). We report herein its crystal and mol­ecular structures along with the Hirshfeld surface analysis.

Structural commentary  

In the title compound (Fig. 1 ▸), the indazole portion is planar to within 0.0171 (10) Å (r.m.s. deviation = 0.0095) with atom C6 the furthest from the mean plane. The nitro group is twisted out of this plane by 6.50 (6)° while the pendant phenyl group makes a dihedral angle of 6.79 (4)° with the plane of the indazole unit. A puckering analysis of the oxazole ring gave parameters Q(2) = 0.1499 (12) Å and φ(2) = 325.7 (5)° with the conformation best described as an envelope on C9.

Supra­molecular features  

In the crystal, the mol­ecules form oblique stacks along the a-axis direction through π–π-stacking inter­actions (Fig. 2 ▸) between the five-membered ring of the indazole unit (N1/N2/C1/C6/C7; centroid Cg2) and the pendant phenyl ring (C12–C17; centroid Cg4) of an adjacent mol­ecule [Cg2⋯Cg4(x,  − y, − + z) = 3.7302 (7) Å; dihedral angle = 3.00 (6)°] and between the six-membered ring of the indazole unit (C1–C6; centroid Cg3) and the pendant phenyl ring of a second neighbour [Cg3⋯Cg4(−1 + x,  − y, − + z) = 3.8286 (7) Å; dihedral angle = 3.65 (6)°]. These stacks are associated into pairs through C7—H7⋯O1 hydrogen bonds (Table 1 ▸ and Figs. 2 ▸ and 3 ▸).

Database survey  

A search of the Cambridge Structural Database (CSD, version 5.39, updates August 2018; Groom et al., 2016 ▸) for the 1-methyl-5-nitro-1H-indazole skeleton yielded six hits. In all of these compounds, the indazole rings are planar as in the title compound. In the crystals of all six compounds, mol­ecules are linked by C—H⋯O hydrogen bonds, similar to what is observed in the crystal of the title compound. The N—O bond lengths vary from ca 1.213–1.236 Å and the C_aromatic—NO₂ bond lengths vary from ca 1.456–1.465 Å. 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.

Hirshfeld surface analysis  

In order to visualize the inter­molecular inter­actions in the crystal of the title compound, a Hirshfeld surface analysis was carried out by using CrystalExplorer17.5 (Turner et al., 2017 ▸). The d _norm representation of the Hirshfeld surface reveals the close contacts of the hydrogen-bond donors and acceptors and other close contacts are also evident. The mol­ecular Hirshfeld surfaces were performed using a standard (high) surface resolution with the three-dimensional d _norm surfaces mapped over a fixed colour scale of −0.191 (red) to 1.051 (blue) Å. The red spots on the surface indicate the inter­molecular contacts involved in the hydrogen bonds. In Fig. 4 ▸, the identified red spot is attributed to the H⋯O close contacts which are due to the C—H⋯O hydrogen bonds (Table 1 ▸).

Figure 4.

Fig. 5 ▸ shows the two-dimensional fingerprint plot for the sum of the contacts contributing to the Hirshfeld surface represented in normal mode. The O⋯H/H⋯O contacts (23.4%) between the oxygen atoms inside the surface and the hydrogen atoms outside the surface, d _e + d _i ∼2.3 Å are shown two symmetrical points at the top, bottom left and right, which are characteristic of C—H⋯O hydrogen bond. The (d _i, d _e) points associated with he H⋯H contacts in this study (36.3%) are characterized by an end point that points to the origin and corresponds to d _i = d _e = 1.08 Å. C⋯H/H⋯C and N⋯H/H⋯N inter­actions (13.4% and 11.4%, respectively) are represented by two symmetrical wings on the left and right sides. In addition, the C⋯C (7.5%), C⋯N/N⋯C (4.7%), O⋯C/C⋯O (2.2%) and O⋯N/N⋯O (0.9%) contacts contribute to the Hirshfeld surface.

The C—H⋯O hydrogen-bond donors and acceptors are shown as blue and red areas around the atoms related with positive (hydrogen-bond donors) and negative (hydrogen-bond acceptors) electrostatic potentials, respectively.

Synthesis and crystallization  

To a solution of 1-allyl-5-nitro-1H-indazole (0.5 g, 2.46 mmol) and benzaldoxime (4.9 mmol, 0.6 g) in chloro­form (20 mL), a solution of sodium hypochlorite 24% (10 mL) was added dropwise to the mixture and stirred at 273 K for 4h. The resulting mixture was washed with water, dried over MgSO₄ and the solvent was evaporated under reduced pressure. The residue was then purified by column chromatography on silica gel using a mixture of hexa­ne/ethyl acetate (v/v = 80/20) as eluent. Colourless crystals were isolated when the solvent was allowed to evaporate (yield: 65%).

Special details

Experimental. The diffraction data were obtained from 3 sets of 400 frames, each of width 0.5° in ω, colllected at φ = 0.00, 90.00 and 180.00° and 2 sets of 800 frames, each of width 0.45° in φ, collected at ω = –30.00 and 210.00°. The scan time was 20 sec/frame.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
