The basic building blocks of the three-dimensional structure of the title compound, C22H19N3O, are helical chains running along the [101] direction and formed by O—H⋯N hydrogen bonds. C—H⋯O hydrogen bonds between chains generate sheets which are then joined together by C—H⋯N hydrogen bonds. The two- and three-dimensional structures also feature two sets of C—H⋯π(ring) interactions.
Keywords: crystal structure; imidazole; hydrogen bond; multi-component reactions.

Structure description
Imidazole derivatives have intensive synthetic interest due to their important biological activities, and many of these compounds are candidates for drug development (Romero et al., 2014). On the other hand, the chemistry of imidazole and its pharmacological actions have attracted many chemists and biologists (Kumar, 2010; Shalini et al., 2010; Bhatnagar et al., 2011). In this context we report here the synthesis and of the title compound.
In the title molecule (Fig. 1), the 4-pyridyl ring makes a dihedral angle of 36.43 (9)° with the imidazole ring. The dihedral angles between the imidazole and the C9–C14 and C15–C20 rings are, respectively, 81.98 (5) and 37.94 (6)°.
In the crystal, molecules form helical chains running parallel to [101] through O1—H1⋯N2i hydrogen bonds (Table 1). These chains are linked into sheets parallel to (101) by C5—H5⋯O1ii hydrogen bonds and the sheets are further associated into a three-dimensional layer structure through C13—H13⋯N3iii hydrogen bonds (Table 1 and Figs. 2 and 3). The two- and three-dimensional structures also feature two sets of C—H⋯π(ring) interactions (Table 1 and Figs. 2 and 3).
Synthesis and crystallization
Benzil (1.06 g; 5 mmol), 4-pyridaldehyde (535 mg, 5 mmol), ammonium acetate (390 mg, 5 mmol) and monoethanolamine (305 mg, 5 mmol) were added to diethyl ammonium hydrogen sulfate (0.342 g, 2 mmol) in an oil bath at room temperature. The resulting mixture was heated at 373 K for an appropriate time. The reaction was monitored by TLC until completion, then washed with water. The resulting solid product was purified by recrystallization from ethanol solution.

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. |
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 > 2sigma(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. |
