Crystal structure and Hirshfeld surface analysis of 4-[4-(1H-benzo[d]imidazol-2-yl)phen-oxy]phthalo-nitrile dimethyl sulfoxide monosolvate.

This work presents the synthesis and structural characterization of [4-(1H-benzo[d]imidazol-2-yl)phen-oxy]phthalo-nitrile, a phthalo-nitrile derivative carrying a benzimidazole moiety. The compound crystallizes as its dimethyl sulfoxide monosolvate, C21H12N4O·(CH3)2SO. The dihedral angle between the two fused rings in the heterocyclic ring system is 2.11 (1)°, while the phenyl ring attached to the imidazole moiety is inclined by 20.7 (1)° to the latter. In the crystal structure, adjacent mol-ecules are connected by pairs of weak inter-molecular C-H⋯N hydrogen bonds into inversion dimers. N-H⋯O and C-H⋯O hydrogen bonds with R 2 1(7) graph-set motifs are also formed between the organic mol-ecule and the disordered dimethyl sulfoxide solvent [occupancy ratio of 0.623 (5):0.377 (5) for the two sites of the sulfur atom]. Hirshfeld surface analysis and fingerprint plots were used to investigate the inter-molecular inter-actions in the crystalline state.

Chemical context

Benzimidazole and its derivatives are some of the oldest and chemically most-studied nitro­gen-containing aromatic heterocyclic compounds (Srestha et al., 2014 ▸). They have a wide range of applications in medicinal chemistry and in biological processes including as anti­cancer, anti­ulcer, anti­fungal and anti-inflammatory agents, and exhibit anti­mycobacterial and anti­oxidant activities (El Rashedy & Aboul-Enein, 2013 ▸; Gaba et al., 2014 ▸; Kathiravan et al., 2012 ▸). They are also used as ligands with fluorescent properties. The fluorescent characteristic of these compounds can be changed by substitution or derivatization of different groups at the NH position of the benzimidazole skeleton.

Phthalo­nitrile derivatives are some of the most widely used precursors for the preparation of phthalocyanines (Pc). The preparation of phthalocyanines is frequently carried out by a cyclo­tetra­merization reaction of phthalo­nitriles. The synthesis of the latter compound family, carrying different functional groups, leads to functionalized phthalocyanines that are of great importance with respect to new mol­ecular materials and targeted applications such as catalysis, liquid crystals, photosensitizers for photodynamic therapy (PDT), non-linear optics, nanotechnology or dye-sensitized solar cells (Torre et al., 2004 ▸; Martínez-Díaz et al., 2011 ▸). In this context, we have recently described a model study, i.e. the synthesis, characterization and Hirshfeld surface analysis of zinc phthalocyanines carrying benzimidazole groups through oxygen bridges to a Zn–Pc core (Sen et al., 2018b ▸). Here we report the synthesis, structural characterization and Hirshfeld surface analysis of a related ligand that crystallizes as its di­methyl­sulfoxide monosolvate, C21H12N4O·(CH3)2SO.

Structural commentary

The mol­ecular components of the title compound are shown in Fig. 1 ▸. The mol­ecular structure of the phthalo­nitrile derivative is constructed from three ring systems, viz. a central phen­oxy ring, a terminal phthalo­nitrile system and a terminal benzimidazole ring. The bond lengths of the cyano groups, 1.132 (6) and 1.137 (6) Å, for C21≡N4 and C20≡N3, respectively, conform well with literature values (Saraçoğlu et al., 2011 ▸). The corresponding C—C≡N angles [179.4 (6) and 177.9 (7)°] are almost linear and are also in good agreement with literature values (Saraçoğlu et al., 2011 ▸; Sen et al., 2018a ▸). The C—C bond lengths of the phenyl rings are in the normal range of 1.356 (5)–1.395 (6) Å, i.e. characteristic of a delocalized system. The dihedral angle of 2.11 (1)° between the fused C1–C6 and C5/N2/C7/N1/C6 rings in the heterocycle indicate a minute deviation from planarity, whereas the attached C8–C13 ring is inclined by 20.7 (1)° to the C5/N2/C7/N1/C6 ring plane.

Supra­molecular features

In the crystal structure, N2—H2⋯O2 and C9—H9⋯O2 inter­molecular hydrogen bonding inter­actions with an (7) graph-set motif are present, whereby the O2 atom acts as an acceptor in both cases (Fig. 1 ▸). There are also weak inter­molecular N2—H2⋯S1A inter­actions between the the N—H group of the imidazole ring and the disordered dimethyl sulfate solvent, and a C23—H23D⋯N4 inter­action between one of the methyl groups of the dimethyl sulfoxide solvent and one of the nitrile N atoms (Table 1 ▸, Fig. 2 ▸). These inter­actions lead to the formation of a three-dimensional supra­molecular network.

Database survey

A search of the Cambridge Structural database (CSD, version 5.40, update November 2018; Groom et al., 2016 ▸) for the 4-[4-(1H-benzo[d]imidazole-2­yl)phen­oxy]phthalo­nitrile moiety revealed two hits. Distinctive bond lengths (N4≡C21, N3≡C20, C7—N2, C5—N2) in the title structure are the same within standard uncertainties as the corresponding bond lengths in the structures of 4-[4-(1H-benzimidazol-2-yl)phen­oxy]benzene-1,2-dicarbo­nitrile monohydrate (HIDHEK; Sen et al., 2018b ▸) or 4-{4-[1-(prop-2-en-1-yl)-1H-benzimidazol-2-yl]phen­oxy}benzene-1,2-dicarbo­nitrile (RELBUI; Sen et al., 2018a ▸). In these structures, the C—O bond lengths vary from 1.363–1.407 Å. In the title mol­ecule, the corresponding bond lengths are 1.367 (5) and 1.406 (4) Å, respectively. In all these structures, the mol­ecules are linked into chains by C—H⋯N hydrogen bonds.

Hirshfeld surface analysis

The Hirshfeld surface analysis (Spackman & Jayatilaka, 2009 ▸) and the associated two-dimensional fingerprint plots (McKinnon et al., 2007 ▸) were performed with CrystalExplorer17 (Turner et al., 2017 ▸). The Hirshfeld surfaces were generated using a standard (high) surface resolution with the three-dimensional surfaces mapped over d norm (Fig. 3 ▸). For the title mol­ecule, the H⋯H inter­actions appear in the middle of the scattered points in the fingerprint plots with a contribution to the overall Hirshfeld surface of 36.1% (Fig. 4 ▸). The contribution from the N⋯H/H⋯N contacts, corresponding to the C—H⋯N inter­actions, is represented by a pair of sharp spikes characteristic of a rather strong hydrogen-bonding inter­action (23.6%). The whole fingerprint region and all other inter­actions are displayed in Fig. 4 ▸. In particular, the O⋯H/H⋯O contacts indicate the presence of inter­molecular C—H⋯O and N—H⋯O inter­actions.

Synthesis and crystallization

2-(4-Hy­droxy-phen­yl)-benzimidazole (1.2 g, 5.71 mmol), which was synthesized by the reaction of o-phenyl­enedi­amine and 4-hy­droxy­benzaldehyde, and 4-nitro­phthalo­nitrile (0.989 g, 5.71 mmol) were dissolved in DMF (15 ml) and degassed by argon in a dual-bank vacuum-gas manifold system. After stirring for 15 min, finely ground anhydrous K2CO3 (0.790 g, 5.71 mmol) was added portion-wise over 2 h under stirring. The suspension solution was maintained at 333 K for 24 h. After completion of the reaction, the crude product was precipitated by pouring into ice–water. The precipitate was collected by filtration, washed with hot water, ethanol, diethyl ether and was finally dried in vacuo. The desired compound was obtained in sufficient purity. The obtained spectroscopic data are accordance with the literature (Khan et al., 2009 ▸). Single crystals for structure analysis were obtained from slow evaporation of a DMSO solution.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.93 Å for aromatic groups, with N—H = 0.86 Å for the imidazole moiety and with 0.96 Å for methyl groups. U iso(H) values were constrained to 1.2–1.5 Ueq of their carrier atoms. The sulfur atom of the di­methyl­sulfate solvent is disordered over two sites (S1A and S1B), with an occupancy ratio of 0.623 (5):0.377 (5).

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.
