The central imidazole ring of the title compound, C24H20Cl2N2O, is twisted with respect to with the planes of the 2,6-dichlorobenzene and two phenyl rings, making dihedral angles of 74.06 (18), 28.52 (17) and 67.65 (18)°, respectively. The phenyl ring not adjacent to the N-bonded 2-hydroxypropyl group shows the greatest twist, presumably to minimize steric interactions. In the crystal, molecules are linked by O—H⋯N and C—H⋯O hydrogen-bond contacts into chains along the a-axis direction. The series of parallel chains form a two-dimensional sheet approximately parallel to the bc diagonal. In addition, C—H⋯π interactions are observed between the sheets. The atoms of the 2-hydroxypropyl group and the N atom of the 1H-imidazole ring to which it is bonded are disordered over two sets of sites, with an occupancy ratio of 0.722 (5):0.278 (5). The structure was refined as an inversion twin.

The title compound has been prepared according to our reported method (Jasinski et al., 2015). Irregular colourless blocks of (I) were obtained by the slow evaporation method using ethanol as a solvent. M.p. 455 K, yield, 94%.
The hydrogen atoms bonded to carbon atoms were located in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.95 - 1.00 Å, and with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for other H atoms. The hydroxyl H atoms were found in difference Fourier maps and were constrained with O—H = 0.82 ± 0.02 Å and U(H) = 1.5 Ueq(O). The N1 atom of the 1H-imidazole ring and the atoms (C4, C5, C6, O1) of the N1-bonded 2-hydroxypropyl group are disordered over two positions in a 0.722 (5):0.278 (5) ratio (N1A, N1B, C4A, C4B, C5A, C5B, C6A, C6B, O1A and O1B). Each pair of atoms in the disordered components N1A, N1B; C4A, C4B; C5A, C5B; C6A, C6B; O1A, O1B were constrained to be equal using the EADP instruction. In addition, the N1A and N1B atoms were set to occupy the same position by an EXYZ command. The (14 1 8), (14 0 - 4), (12 2 - 1), (13 1 3), (4 3 - 2), (14 2 - 4), (13 2 11), (12 3 - 2), (12 5 - 2), (11 6 4), (11 2 0) and (10 7 3) reflections were omitted owing to very bad agreement.
As part of an ongoing study on synthesis of imidazole based amino
(Akkurt et al., 2013; Mohamed et al., 2013a,b; Jasinski et al., 2015) we report herein the synthesis and of the title compound, 1-[2-(2,6-dichlorophenyl)-4,5-diphenyl-1H-imidazol-1-yl] propan-2-ol.In the title compound, Fig. 1, the central 1H-imidazole ring (N1B/N2/C1—C3) is twisted with respect to with the planes of the benzene, C7–C12, and two phenyl, C13–C18 and C19–C24, rings, making dihedral angles of 74.06 (18), 28.52 (17) and 67.65 (18)°, respectively. The dihedral angle between the C13–C18 and C19–C24 phenyl rings is 69.15 (18)°. The C7–C12 benzene ring makes dihedral angles of 87.01 (18) and 52.65 (18)° with the phenyl rings, C13–C18 and C19–C24, respectively. The bond lengths are normal and comparable to those reported for similar compounds (Mohamed et al., 2012, 2013a,b; Akkurt et al., 2013; Jasinski et al., 2015).
In the crystal, O—H···N and C—H···O hydrogen bonds (Table 1) link molecules into chains along the a axis direction and the series of parallel chains displayed in Fig. 2 form a two-dimensional sheet approximately parallel to the bc diagonal. C—H···π interactions (Table 1) are also observed in the packing of the title compound.

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. Refined as a 2-component inversion twin. |

As part of an ongoing study on synthesis of imidazole based amino alcohols (Akkurt et al., 2013; Mohamed et al., 2013a,b; Jasinski et al., 2015) we report herein the synthesis and crystal structure of the title compound, 1-[2-(2,6-dichlorophenyl)-4,5-diphenyl-1H-imidazol-1-yl] propan-2-ol.
In the title compound, Fig. 1, the central 1H-imidazole ring (N1B/N2/C1—C3) is twisted with respect to with the planes of the benzene, C7–C12, and two phenyl, C13–C18 and C19–C24, rings, making dihedral angles of 74.06 (18), 28.52 (17) and 67.65 (18)°, respectively. The dihedral angle between the C13–C18 and C19–C24 phenyl rings is 69.15 (18)°. The C7–C12 benzene ring makes dihedral angles of 87.01 (18) and 52.65 (18)° with the phenyl rings, C13–C18 and C19–C24, respectively. The bond lengths are normal and comparable to those reported for similar compounds (Mohamed et al., 2012, 2013a,b; Akkurt et al., 2013; Jasinski et al., 2015).
In the crystal, O—H···N and C—H···O hydrogen bonds (Table 1) link molecules into chains along the a axis direction and the series of parallel chains displayed in Fig. 2 form a two-dimensional sheet approximately parallel to the bc diagonal. C—H···π interactions (Table 1) are also observed in the packing of the title compound.
