The title compound, C24H24N2O4·CH3CN, a disubstituted benzimidazole, crystallized as an acetonitrile monosolvate. The benzene ring of the 2-ethoxy-6-methylphenol substiuent is approximately perpendicular to the nearly planar benzimidazole ring system [maximum deviation = 0.016 (1) Å], making a dihedral angle of 84.27 (8)°. The benzene ring of the 2-ethoxyphenol substituent is inclined to the benzimidazole mean plane by 29.68 (8)°. The dihedral angle between the benzene rings is 80.36 (9)°. In the molecule, there are strong O—H⋯N and O—H⋯O hydrogen bonds. In the crystal, molecules are connected by bifurcated O—H⋯(O,O) hydrogen bonds, forming chains propagating along [010].

1,2-Phenylenediamine (0.7568 g, 6.998 mmol) and 3-ethoxysalicylaldehyde (2.3269 g, 14.003 mmol) in EtOH (20 ml) were stirred for 5 h at room temperature. After evaporation of the solvent, the residue was recrystallized from a mixture of acetone and ether (1:2, v:v) at 188 K, to give an orange powder (1.9139 g). Orange block-like crystals, suitable for X-ray analysis, were obtained by slow evaporation of a CH3CN/acetone solution at room temperature.
The hydroxy H atoms were located from a difference Fourier map and refined freely. C-bound H atoms were included in calculated positions and treated as riding atoms: C—H = 0.95, 0.98 and 0.99 Å for CH, CH3 and CH2 H-atoms, respectively, with Uiso(H) = k× Ueq(parent C-atom), where k = 1.5 for CH3 H-atoms and = 1.2 for other H-atoms.

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

The crystal structure of the related compound, 2-methoxy-6-(1-(3-methoxy-2-hydroxybenzyl)-2,3-dihydro-1H-benzo[d]imidazol-2-yl)phenol monohydrate, has been reported on previously (Al-Douh et al., 2009).
The title compound contains a disubstituted benzimidazole molecule and a lattice solvent molecule (Fig. 1). One of the benzene rings (C17-C22) is approximately perpendicular to the nearly planar benzimidazole ring system [maximum deviation = 0.016 (1) Å], making a dihedral angle of 84.27 (8)°, whereas the other ring (C8-C13) is somewhat inclined to the benzomidazole mean plane with a dihedral angle of 29.68 (8)°. The dihedral angle between the benzene rings is 80.36 (9)°. The compound reveals strong intramolecular O—H···N and O—H···O hydrogen bonds, forming six- and five-membered rings, respectively (Fig. 1 and Table 1).
In the crystal, molecules are connected by bifurcated O—H···O,O hydrogen bonds, forming chains along the b axis (Fig. 2 and Table 1).
