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

ABSTRACT: 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?? inter-actions and ?-? stacking [centroid-centroid distances = 3.8834?(18) and 3.9621?(17)?Å] inter-actions.

Project description:The title compound, C24H19ClN2, crystallizes with two independent mol-ecules in the asymmetric unit. The prop-2-enyl substituents on the imidazole rings adopt similar conformations in the two mol-ecules. The 4-and 5-substituted phenyl rings and the benzene ring make dihedral angles of 67.06 (8), 5.61 (8) and 41.09 (8)°, respectively, with the imadazole ring in one mol-ecule and 71.53 (8), 28.85 (8) and 41.87 (8)°, respectively, in the other. The crystal structure features C-H⋯π inter-actions and weak π-π stacking inter-actions [centroid-centroid distances = 3.6937 (10) and 4.0232 (10) Å] between the chloro-phenyl rings, which form a three-dimensional supramolecular structure.

4-(1-Allyl-4,5-diphenyl-1H-imidazol-2-yl)-N,N-dimethyl-aniline.

Project description:The title compound, C26H25N3, crystallizes with four independent mol-ecules, 1-4, in the asymmetric unit of the triclinic unit cell. The allyl substituents on the imidazole rings adopt similar conformations in all four mol-ecules. The imadazole and the 4-and 5-substituted phenyl rings of two pairs of molecules in the asymmetric unit stack parallel to (110). In contrast, the dimethyl-aniline systems in these pairs of mol-ecules are almost normal to one another, with dihedral angles of 85.84?(10) and 85.65?(10)° between the benzene rings of the two dimethyl-aniline fragments of mol-ecules 1 and 2, and 3 and 4, respectively. The crystal structure features an extensive series of C-H?? inter-actions that link the mol-ecules into undulating rows along the c axis. The crystal studied was a pseudo-merohedral twin with twin law [-100, 0-10, 111] and the BASF parameter refined to 0.513?(3).
