In the 10H9N2O2+·Cl−·2H2O, the components are linked by O—H⋯O, N—H⋯O, O—H⋯Cl and N—H⋯Cl hydrogen bonds. In the cation, the imidazole ring is oriented at a dihedral angle of 13.67 (17)° with respect to the benzene ring. In the crystal, π–π stacking occurs between nearly parallel benzene rings, which are oriented at a dihedral angle of 3.4 (1)°, the centroid–centroid distance being 3.798 (3) Å.

A 150 ml round-bottom flask was charged with a magnetic stirrer and a reflux condenser, iminazole (44 mmol), K2CO3 (6.00 g, 43 mmol), 30 ml DMSO and a little Aliquat 336 were added. 4-Fluorobenzaldehyde (4.5 ml, 42 mmol) was added dropwise to the mixture at 363 K and stirred for 15 min. Then the reaction mixture was refluxed for 24 h at 353 K, cooled to room temperature, poured into 150 ml ice-water and filtered. The primrose yellow crude product was obtained, washed with distilled water, and dried in vacuo at room temperature, then purified by recrystallization with ethyl acetate to give the desired analytical pure intermediate products. Intermediate product (12.5 mmol) and 15 ml 20% (wt) NaOH (aq) were added to a round-bottom flask equipped with a magnetic stirrer and a reflux condenser at 333 K for 30 min. Then AgNO3 (4.00 g, 24 mmol) was added to the mixture group by group. The reaction mixture was refluxed for 24 h at 333 K, cooled to room temperature and filtered. Excessive HCl (1 M) was added to the filtrate and adjust pH to 2, a great deal of sediments were obtained and then filtered. The crude product was recrystallized from ethanol-water solution.
Water H atoms were located in a difference Fourier map and refined isotropically. Other H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with O—H = 0.82 and C—H = 0.93 Å, Uiso(H) = 1.5Ueq(O) and 1.2Ueq(C).

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. |

Imidazol - based materials had been investigated for their electrical and optical properties. Beside, the introduction about the structure of its complex has been reported (Nie et al., 2009). The title molecule that we has designed and synthesized is a good intermediate and penetratingly investigated. In the title molecule(I) (Fig.1), the bond lengths and angles show normal values. The imidazole ring is twisted out of the plane of the center benzene ring at a dihedral angle of 13.67 (17)°. In the title molecule (I) (Fig.2), the neighboring molecules connect through O—H···O, N—H···O, O—H···Cl and N—H···Cl hydrogen bonds (Table 1). π–π stacking is observed between nearly parallel benzene rings, the centroids distance being 3.798 (3) Å.
