2-(4-Chloro-phen-yl)-4,5-diphenyl-1-(prop-2-en-1-yl)-1H-imidazole

Crystal structure of 1-[2-(4-chloro-phen-yl)-4,5-diphenyl-1H-imidazol-1-yl]propan-2-ol

The title compound, C24H21ClN2O, crystallizes with two unique mol-ecules in the asymmetric unit. In each mol-ecule, the central imidazole ring is substituted at the 2-, 4- and 5-positions by benzene rings. The 2-substituted ring carries a Cl atom at the 4-position. One of the imidazole N atoms in each mol-ecule has a propan-2-ol substituent. In the crystal, a series of O-H⋯N, C-H⋯O and C-H⋯Cl hydrogen bonds, augmented by several C-H⋯π(ring) inter-actions, generate a three-dimensional network of mol-ecules stacked along the a-axis direction.

Prop-2-en-1-yl 4-(4,5-diphenyl-1H-imidazol-2-yl)benzoate

The title compound, C25H20N2O2, crystallized with two mol-ecules in the asymmetric unit, in one of which the atoms of the terminal propenyl group are disordered over two sets of sites, with a refined occupancy ratio of 0.870 (4):0.130 (4). The central imidazole ring makes dihedral angles of 25.51 (11), 40.73 (11) and 27.36 (11)° with the three pendant rings in one molecule and 22.56 (10), 60.72 (10) and 5.85 (10)° in the other. In the crystal, mol-ecules are linked by N-H⋯N and C-H⋯O hydrogen bonds, forming a three-dimensional network. The crystal structure also features C-H⋯π inter-actions and π-π stacking [centroid-centroid distances = 3.8834 (18) and 3.9621 (17) Å] inter-actions.

2-(2,5-Di-meth-oxy-phen-yl)-4,5-diphenyl-1-(prop-2-en-1-yl)-1H-imidazole

In the title compound, C26H24N2O2, the two phenyl and the 2,5-di-meth-oxy-phen-yl rings are inclined to the imidazole ring at dihedral angles of 30.38 (8), 56.59 (9) and 73.11 (9)°, respectively. In the crystal, mol-ecules are linked by pairs of C-H⋯O inter-actions into centrosymmetric dimers with graph-set notation R 2 (2)(8). C-H⋯π inter-actions are also observed.

2,4,5-Triphenyl-1-(prop-2-en-1-yl)-1H-imidazole

In the title compound, C24H20N2, one of the ring C atoms and one of the ring N atoms are disordered over two sets of sites in a 0.615 (3):0.385 (3) ratio. The two parts of the disordered imidazole ring adopt an envelope conformation, with the undisordered ring N atom as the flap, displaced by -0.118 (6) and 0.226 (7) Å, respectively, in the two disorder components from the plane through the other ring atoms. The crystal structure features C-H⋯N hydrogen bonds and C-H⋯π inter-actions, which lead to the formation of infinite chains along [010].
