Abstract
In the title compound, C21H12N4O·H2O, the five-membered ring is essentially planar with a maximum deviation of 0.004 (2) Å. An N—H⋯O hydrogen bond connects the organic and water molecules. In the crystal, O—H⋯N hydrogen bonds link molecules into a two-dimensional network parallel to (100). Hirshfeld surface analyses and two-dimensional fingerprint plots were used to quantify the intermolecular interactions present in the crystal, indicating that the most important contributions for the crystal packing are from H⋯H (28.7%), C⋯H/H⋯C (27.1%), N⋯H/H⋯N (26.4%), C⋯N/N⋯C (6.1%), O⋯H/H⋯O (3.7%) and C⋯C (6.0%) interactions.
Chemical context
Benzimidazole derivatives, as nitrogen-containing aromatic heterocyclic compounds, are a very important class owing to their biological importance (Preston, 2008 ▸). They are widely used as antiulcer, antifungal and antimycobacterial compounds (Patil et al., 2008 ▸) and have also attracted attention as organic fluorescent chromophores in recent years (Verdasco et al., 1995 ▸). Phthalonitrile derivatives are widely used precursors for the preparation of phthalocyanines, an important class of molecules not only as commercial pigments but also as important functional materials in many areas (Sharman et al., 2003 ▸). The preparation of phthalocyanines is carried out by cyclotetramerization reactions of phthalonitriles. The development of benzimidazole derivative-substituted phthalocyanines from the related phthalonitriles is crucial in terms of achieving a combination of functional groups.
We now report for the first time that benzimidazole groups linked directly through oxygen bridges to phthalonitrile units are new functionalized materials. We have described the synthesis, characterization and spectroscopic behavior of the synthesized starting phthalonitrile compound (Sen et al., 2018 ▸).
Structural commentary
The asymmetric unit of the title compound contains one independent molecule and one water molecule (Fig. 1 ▸). The five-membered ring is essentially planar with maximum deviations of 0.004 (2) Å for atom N2 and −0.004 (2) Å for C5 and the N1=C7, N1—C6 and C5—C6 bond lengths are 1.324 (3), 1.388 (3) and 1.391 (3) Å, respectively. The dihedral angle between the fused C1–C6 and C5/N2/C7/N1/C6 rings is 1.71 (13)° while the C8–C13 ring subtends a dihedral angle of 16.03 (12)° with the C5/N2/C7/N1/C6 ring plane. The C14–C19 ring makes a dihedral angle of 83.55 (11)° with the C8–C13 ring.

Supramolecular features
In the crystal, an N2—H2⋯O2 hydrogen bond connects the organic and water molecules (Table 1 ▸). O2—H2C⋯N1 hydrogen bonds connect the molecules into a two-dimensional network parallel to (100) (Table 1 ▸, Fig. 2 ▸).

Hirshfeld surface analysis
Crystal Explorer17.5 (Turner et al., 2017 ▸) was used to analyse the interactions in the crystal. Figs. 3 ▸ and 4 ▸ show the Hirshfeld surfaces mapped over d norm. with a fixed colour scale of −0.4353 (red) to 1.4359 (blue) a.u. where red spots indicate the regions of donor–acceptor interactions (Aydemir et al., 2018 ▸; Kansiz et al., 2018 ▸; Şen et al., 2017 ▸; Gümüş et al., 2018 ▸)·There are five red spots in the d norm surface (Fig. 3 ▸); these represent the N-acceptor atoms involved in the interactions listed in Table 1 ▸.

Hirshfeld surfaces mapped over d norm to visualize the intermolecular interactions.
The overall two-dimensional fingerprint plot and those showing different contacts are characterized in Fig. 5 ▸, together with their relative contributions to the Hirshfeld surface. H⋯H/H⋯H interactions, contributing 28.7% to the overall crystal packing, are some of the important interactions, and are shown in Fig. 6 ▸ as an end point that points to the origin with the tips at d i = d e = 1.1 Å. The C⋯H/H⋯C contacts in the structure, with a 27.1% contribution to the Hirshfeld surface, have a symmetrical distribution of points, with the tips at d e + d i = 2.7 Å. The contribution from the N⋯H/H⋯N contacts, corresponding to C—H⋯N and O—H⋯N interactions, is represented by a pair of sharp spikes characteristic of a strong hydrogen-bond interaction (26.4%). The O⋯H/H⋯O contacts, with a 3.7% contribution, appear with the points of low densities. Lastly, the C⋯N/N⋯C, C⋯C/C⋯C and O⋯C/C⋯O interactions in the structure with 6.1, 5.5 and 1.4% contributions, respectively, have symmetrical distributions of points.

Database survey
There are no direct precedents for the structure of the title compound in the crystallographic literature (Groom et al., 2016 ▸). However, there are several precedents for the 2-(4-hydroxyphenyl)benzimidazole, including 4-[4-(1-allyl-1H-benzo[d]imidazole-2yl)phenoxy]phthalonitrile (Sen et al., 2018 ▸), 4-(1H-benzo[d]imidazol-2-yl)phenol (Zhan et al., 2007 ▸), 2-(4-methoxyphenyl)-1H-benzimidazole (Moreno-Diaz et al., 2006 ▸) and 4-(1H-benzimidazol-2-yl)phenol (Zhou et al., 2006 ▸).
Synthesis and crystallization
The synthesis of the title compound (Fig. 7 ▸) was described by Sen et al. (2018 ▸). 4-[4-(1H-Benzo[d]imidazole-2yl)phenoxy]phthalonitrile, 4-nitrophthalonitrile (0.989 g, 5.71 mmol) and 2-(4-hydroxyphenyl)benzimidazole (1.2 g, 5.71 mmol) were dissolved in DMF (15 mL) under argon. After stirring for 15 min, anhydrous K2CO3 (0.790 g, 5.71 mmol) was added portionwise over 2 h with efficient stirring. The suspension was maintained at 333 K for 24 h. The progress of the reaction was monitored by TLC using a CHCl3/EtOAc (10/1) solvent system. After the reaction was observed to be complete, the resulting mixture was poured into an ice–water mixture. The immediate precipitate was collected by filtration, washed with hot water, ethanol and diethyl ether and dried in vacuo. The desired pure compound was obtained in sufficient purity, yield: 96% (1.84 g). m.p. 421 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. |
