Hirshfeld surface analysis and crystal structure of 7-meth­oxy-5-methyl-2-phenyl-11,12-di­hydro-5,11-methano-1,2,4-triazolo[1,5-c][1,3,5]benzoxadiazo­cine

In the crystal, classical N—H⋯N hydrogen bonds, weak C—H⋯O hydrogen bonds and weak C—H⋯π inter­actions link the mol­ecules into a three-dimensional supra­molecular network.

Abstract

The title compound, C₁₉H₁₈N₄O₂, crystallizes with two independent mol­ecules in the asymmetric unit. The triazole ring is inclined to the benzene rings by 9.63 (13) and 87.37 (12)° in one mol­ecule, and by 4.46 (13) and 86.15 (11)° in the other. In the crystal, classical N—H⋯N hydrogen bonds, weak C—H⋯O hydrogen bonds and weak C—H⋯π inter­actions link the mol­ecules into a three-dimensional supra­molecular network. Hirshfeld surface analysis and two-dimensional fingerprint plots were used to investigate the inter­molecular inter­actions present in the crystal, indicating that the most important contributions for the crystal packing are from H⋯H (51.4%), H⋯C/C⋯H (26.7%), H⋯O/O⋯H (8.9%) and H⋯N/N⋯H (8%) inter­actions.

Chemical context  

One of the earliest known multi-component reactions (MCRs) is the Biginelli multi-component cyclo­condensation. Its variations are still a timely subject for research because of the near unlimited scope of this approach and the constant demand for mol­ecular diversity of small mol­ecules in many areas such as drug discovery, combinatorial and medicinal chemistry (Kappe, 2000 ▸; Slobbe et al., 2012 ▸). As we had previously synthesized a type of oxygen-bridged Biginelli compounds derivatives, (Gümüş et al., 2017 ▸), we decided to examine the structure of this heterocyclic system by X-ray analysis (Aydemir et al., 2018 ▸; Gümüş et al., 2018 ▸). In this study, a novel Biginelli-like assembly of 3-amino-5-(phen­yl)-1,2,4-triazole with acetone and 2-hy­droxy-3-meth­oxy­benzaldehyde has been developed to offer easy access to 7-meth­oxy-5-methyl-2-(phen­yl)-11,12-di­hydro-5,11-methano[1,2,4]triazolo[1,5-c][1,3,5]benzoxa­diazo­cine compounds as examples of a new class of heterocycles.

Structural commentary  

The asymmetric unit of the compound contains two independent mol­ecules (Fig. 1 ▸), linked by N4—H4⋯N5 and N8—H8⋯N1 hydrogen bonds, which stabilize the mol­ecular structure (Table 1 ▸, Fig. 1 ▸ and 2 ▸). The C11—O1, C13—O1, C18—O2, C19—O2, C30—O3, C32—O3, C37—O4 and C38—O4 bond lengths are all in agreement with single-bond character. The C—O bond distances observed are lower than in the literature [1.364 (4), 1.390 (4), 1.428 (4) and 1.443 (4) Å; Aydemir et al., 2018 ▸). The triazole ring is inclined to the benzene rings by 9.63 (13) and 87.37 (12)° in one mol­ecule, and by 4.46 (13) and 86.15 (11)° in the other. The ring N3/C8/N4/C9–C11 is inclined to the ring N2/C7/N1/C8/N3 by 5.80 (14)° and to the ring C9–C11/O1/C13/C14 by 86.9 (6)° [equivalent values of 6.55 (11) and 85.29 (11)°, respectively, in the other independent mol­ecule].

Supra­molecular features  

In the crystal, weak C—H⋯O interactions link the pairs of independent molecules into layers parallel to (100) (Table 1 ▸; Fig. 2 ▸). The layers are further connected by weak C—H⋯π inter­actions, generating a three-dimensional supra­molecular structure.

Hirshfeld surface analysis  

Hirshfield surface analysis was performed using CrystalExplorer (Turner et al., 2017 ▸) to qu­antify the various inter­molecular inter­actions in the synthesized complex. The Hirshfeld surfaces of the title compound mapped over d _norm, d _i and d _e are illustrated in Fig. 3 ▸. The red spots on the surface indicate the intermolecular contacts involved in strong hydrogen bonding and interatomic contacts (Sen et al., 2018 ▸) and correspond to C—H⋯O hydrogen bonds in the title compound (Figs. 3 ▸ and 4 ▸). The Hirshfeld surfaces were calculated using a standard (high) surface resolution with the three-dimensional d_norm surfaces mapped over a fixed colour scale of −0.249 (red) to 1.531 (blue) a.u..

Fig. 5 ▸ shows the two-dimensional fingerprint of the sum of the contacts contributing to the Hirshfeld surface represented in normal mode. The graph shown in Fig. 6 ▸ a (H⋯H) shows the two-dimensional fingerprint of the (d _i, d _e) points associated with hydrogen atoms. It is characterized by an end point that points to the origin and corresponds to d _i = d _e = 1.2 Å, which indicates the presence of the H⋯H contacts in this study (51.4%). The graph shown in Fig. 6 ▸ b (H⋯C/C⋯H) shows the contacts between the carbon atoms inside the surface and the hydrogen atoms outside the surface of Hirshfeld and vice versa with two symmetrical wings on the left and right sides (26.7%). Two symmetrical points at the top, bottom left and right with d _e + d _i 2.5 Å indicate the presence of the H⋯C/C⋯H contacts. Further, there are H⋯O/O⋯H (8.9%), H⋯N/N⋯H (8%), C⋯C (3.2%) and C⋯O/O⋯C (1.0%) contacts.

The 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  

The synthesis (Fig. 8 ▸) of the title compound was described by Gümüş et al. (2017 ▸). 3-Amino-5-(phen­yl)-1,2,4-triazole (1.0 mmol), 2-hy­droxy-3-meth­oxy­benzaldehyde (1.0 mmol), acetone (0.22 mL, 3.0 mmol), and abs. EtOH (2.0 mL) were mixed in a microwave process vial, after which a 4 N solution of HCl in dioxane (0.07 mL, 0.3 mmol) was added. The mixture was irradiated at 423 K for 30 min. The reaction mixture was cooled by an air flow and stirred for 24 h at room temperature for complete precipitation of the product. The precipitate was filtered off, washed with EtOH (1.0 mL) and Et₂O (3 × 1.0 mL), and dried. The compound was obtained in the form of a white solid with %53 yields. It was recrystallized from ethanol.

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.
