Crystal structure and Hirshfeld surface analysis of 2-[(1,3-benzoxazol-2-yl)sulfan­yl]-N-(2-meth­oxy­phen­yl)acetamide

In the title compound, there are two intra­molecular N—H⋯O and N—H⋯N hydrogen bonds, forming S(5) and S(7) ring motifs, respectively. In the crystal, pairs of C—H⋯O hydrogen bonds link mol­ecules into inversion dimers with (14) ring motifs, stacked along the b-axis direction. The inversion dimers are linked by C—H⋯π and π–π-stacking inter­actions, forming a three-dimensional network.

Abstract

In the title compound, C₁₆H₁₄N₂O₃S, the 1,3-benzoxazole ring system is essentially planar (r.m.s deviation = 0.004 Å) and makes a dihedral angle of 66.16 (17)° with the benzene ring of the meth­oxy­phenyl group. Two intra­molecular N—H⋯O and N—H⋯N hydrogen bonds occur, forming S(5) and S(7) ring motifs, respectively. In the crystal, pairs of C—H⋯O hydrogen bonds link the mol­ecules into inversion dimers with R ² ₂(14) ring motifs, stacked along the b-axis direction. The inversion dimers are linked by C—H⋯π and π–π-stacking inter­actions [centroid-to-centroid distances = 3.631 (2) and 3.631 (2) Å], forming a three-dimensional network. Two-dimensional fingerprint plots associated with the Hirshfeld surface show that the largest contributions to the crystal packing come from H⋯H (39.3%), C⋯H/H⋯C (18.0%), O⋯H/H⋯O (15.6) and S⋯H/H⋯S (10.2%) inter­actions.

Chemical context  

As a part of our ongoing research on synthesis and screening of pharmacological activities of compounds with a benzoxazole ring, which is known to produce a wide range of biological activities (Aggarwal et al., 2017 ▸; Gautam et al., 2012 ▸), we have focused on the synthesis of 3-substituted benzoxazolone-2-thione and S-substituted benzoxazole-2-thiol derivatives. It is well known that alkyl­ation of benzoxazolone-2-thione leads to the S-alkyl­ated derivatives instead of N-alkyl­ated ones (Xiang et al., 2012 ▸; Rakse et al., 2013 ▸; Yurttaş et al., 2015 ▸). In this manner, the title compound was synthesized as a member of the target S-substituted benzoxazole-2-thiol series. The title compound is listed in the literature with registry number CASRN 331966-95-1 but corresponding scientific reference data are not available.

Structural commentary  

In the mol­ecular structure of the title compound (Fig. 1 ▸), the 1,3-benzoxazole ring system (N1/O1/C1–C7) is essentially planar (r.m.s deviation = 0.004 Å) and makes a dihedral angle of 66.16 (17)° with the benzene ring (C10–C15) of the meth­oxy­phenyl group. Atoms O3 and C16 deviate from the benzene ring by −0.008 (3) and 0.099 (6) Å, respectively. The torsion angle C7—S1—C8—C9 = −87.7 (3)°, S1—C8—C9— N2 = 91.6 (4)° and C8—C9—N2—C10 = −178.8 (3)°. The C7—S1 [1.740 (4) Å] and C8—S1 [1.812 (4) Å] bond lengths are comparable with those reported for three similar structures, viz. 2-[(4,6-di­amino­pyrimidin-2-yl)sulfan­yl]-N-(2-meth­yl­phen­yl)acetamide (1.763 and 1.805 Å, respectively; Subasri et al., 2014 ▸), 2-[(4,6-di­amino­pyrimidin-2-yl)sulfan­yl]-N-(2,4-di­methyl­phen­yl)acetamide [1.7650 (14) and 1.8053 (16) Å, respectively; Choudhury et al., 2017 ▸] and 2-[(4,6-di­amino­pyrimidin-2-yl)sulfan­yl]-N-(3-meth­oxy­phen­yl) acetamide [1.7721 (17) and 1.8126 (18) Å, respectively; Choudhury et al., 2017 ▸]. The two intra­molecular hydrogen bonds, N2—HN2⋯O3 and N2—HN2⋯N1, form S(5) and S(7) ring motifs, respectively (Table 1 ▸, Fig. 1 ▸).

Supra­molecular features  

In the crystal, pairs of C—H⋯O hydrogen bonds link the mol­ecules into inversion dimers with (14) ring motifs, stacking along the b-axis direction. These dimers are linked by C—H⋯π (Table 1 ▸, Fig. 2 ▸) and π–π-stacking inter­actions [Fig. 2 ▸; distances of 3.631 (2) and 3.631 (2) Å between the centroids of the five- and opposite six-membered rings of the 1,3-benzoxazole ring system of adjacent mol­ecules], forming a three-dimensional network (Fig. 3 ▸).

Hirshfeld surface analysis  

In order to explore the role of weak inter­molecular inter­actions in the crystal packing, Hirshfeld surfaces (d _norm) and the related two-dimensional fingerprint plots were generated using CrystalExplorer17.5 (Spackman & Jayatilaka, 2009 ▸; Wolff et al., 2012 ▸). The three-dimensional mol­ecular Hirshfeld surfaces were generated using a high standard surface resolution over a colour scale of −0.1599 to 1.2011 a.u. for d _norm (Fig. 4 ▸). The red spots in the Hirshfeld surface represent short N⋯H/H⋯N and O⋯H/H⋯O contacts. On the shape-index surface (Fig. 5 ▸), convex blue regions represent hydrogen-donor groups and concave red regions represent hydrogen-acceptor groups. In addition, concave red regions represent C—H⋯π and π–π inter­actions.

View of the three-dimensional Hirshfeld surface of the title compound plotted over electrostatic potential energy in the range −0.0500 to 0.0500 a.u. using the STO-3 G basis set at the Hartree–Fock level of theory. Hydrogen- bond donors and acceptors are shown as blue and red regions around the atoms corresponding to positive and negative potentials, respectively.

The bright-red spots indicate their roles as the respective donors and/or acceptors; they also appear as blue and red regions corresponding to positive and negative potentials on the Hirshfeld surface mapped over electrostatic potential (Spackman et al., 2008 ▸) shown in Fig. 6 ▸. The blue regions indicate the positive electrostatic potential (hydrogen-bond donors), while the red regions indicate the negative electrostatic potential (hydrogen-bond acceptors).

The two-dimensional fingerprint plots (Fig. 7 ▸) qu­antify the contributions of each type of inter­molecular inter­action to the Hirshfeld surface (McKinnon et al., 2007 ▸). The largest contribution (39.3% of the surface) is from H⋯H contacts (Table 2 ▸), which represent van der Waals inter­actions, followed by C⋯H/H⋯C contacts involved in C—H⋯π inter­actions (18.0%). Finally, the O⋯H/H⋯O (15.6%), S⋯H/H⋯S (10.2%) and C⋯C (4.5%) contacts correspond to hydrogen bonds and π–π inter­actions, respectively. The percentage contributions to the Hirshfeld surface of the various inter­atomic contacts are given in Table 3 ▸.

In the crystals of JARPOK and JARPUQ, mol­ecules are linked by pairs of N—H⋯N hydrogen bonds, forming inversion dimers with (8) ring motifs. In the crystal of JARPOK, the dimers are linked by bifurcated N—H⋯(O,O) and C—H⋯O hydrogen bonds, forming layers parallel to (100). In the crystal of JARPUQ, the dimers are linked by N—H⋯O hydrogen bonds, also forming layers parallel to (100). The layers are linked by C—H⋯F hydrogen bonds, forming a three-dimensional architecture.

In the crystal of GOKWIO, mol­ecules are linked via pairs of N—H⋯N hydrogen bonds, forming inversion dimers with an (8) ring motif. The dimers are linked by N—H⋯O and C—H⋯O hydrogen bonds, forming sheets parallel to (100).

In the crystals of JAXFIA and JAXFOG, a pair of N—H⋯N hydrogen bonds links the mol­ecules, forming inversion dimers with (8) ring motifs. In JAXFIA, the dimers are linked by N—H⋯O and C—H⋯O hydrogen bonds, enclosing (14), (11) and (7) ring motifs, forming layers parallel to the (100) plane. There is also an N—H⋯π inter­action present within the layer. In JAXFOG, the inversion dimers are linked by N—H⋯O hydrogen bonds enclosing an (18) ring motif. The presence of N—H⋯O and C—H⋯O hydrogen bonds generate an (6) ring motif. The combination of these various hydrogen bonds results in the formation of layers parallel to the (11) plane.

In the crystal of PAXTEP, mol­ecules are consolidated in the form of polymeric chains along [010] as a result of N—H⋯O hydrogen bonds, which generate (18) and (22) loops. The polymeric chains are inter­linked through C—H⋯O inter­action and complete (8) ring motifs.

Synthesis and crystallization  

The starting materials, 2-mercaptobenzoxazole and α-chloro-N-(o-meth­oxy­phen­yl)acetamide, were synthesized according to literature methods (Maske et al., 2012 ▸; Ren et al., 2015 ▸). For the synthesis of the title compound, 2-mercaptobenzoxazole (1 eq) and α-chloro-N-(o-meth­oxy­phen­yl) acetamide (1 eq) were heated in acetone under reflux for 1.5 h in the presence of K₂CO₃ (1 eq). The reaction mixture was then cooled to room temperature and cold water was added until precipitation was complete. The precipitate was filtered, washed with cold water and dried. The crude product was crystallized from methanol (yield 31%); m.p. 370 K.

Special details

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.
