2-(3,4-Dimeth-oxy-phen-yl)-4,5-diphenyl-1-(prop-2-en-1-yl)-1H-imidazole.

ABSTRACT: In the title compound, C(26)H(24)N(2)O(2), the planar 1H-imidazole ring makes dihedral angles of 35.78?(4), 26.35?(5) and 69.75?(5)°, respectively, with the dimeth-oxy-phenyl ring and the phenyl rings in the 4- and 5-positions. In the crystal, C-H?O hydrogen bonds connect neighbouring mol-ecules, forming infinite chains running along the b axis. Furthermore, the crystal structure exhibits a C-H-?? inter-action between a methyl H atom and a phenyl ring from an adjacent mol-ecule.

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

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.

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

Project description:The asymmetric unit of the title compound, C(25)H(22)N(2)O, contains two independent mol-ecules (A and B), with significantly different conformations. In mol-ecule A, the central imidazole ring makes dihedral angles of 88.26?(10) and 12.74?(11)° with the two phenyl rings, and 22.06?(9)° with the benzene ring. In mol-ecule B, one of the phenyl rings is disordered over two sites, each having an occupancy of 0.5. Here the central imidazole ring forms dihedral angles of 79.24?(10)° with the ordered phenyl ring, and 3.5?(5) and 22.6?(5)° with the two parts of the disordered phenyl ring. The dihedral angle involving the benzene ring is 67.49?(10)°. The -N-C(H(2))-C(H)-C(H(2)) torsion angles of the prop-1-ene group in the two mol-ecules are very similar, 0.5?(3) and 1.3?(4)° for mol-ecules A and B, respectively. The crystal structure is stabilized by C-H?? inter-actions.
