ABSTRACT
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 85.84â (10) and 85.65â (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-Hâ¯π 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 0.513â (3).
ABSTRACT
The title compound, C27H28N2O, is a lophine (2,4,5-triphenyl-1H-imidazole) derivative with an n-pentyl chain on the amine N atom and a 4-meth-oxy substituent on the benzene ring. The two phenyl and meth-oxy-benzene rings are inclined to the imidazole ring at angles of 25.32â (7), 76.79â (5) and 35.42â (7)°, respectively, while the meth-oxy substituent lies close to the plane of its benzene ring, with a maximum deviation of 0.126â (3)â Å for the meth-oxy C atom. In the crystal, inversion dimers linked by pairs of C-Hâ¯O hydrogen bonds generate R2(2)(22) loops. These dimers are stacked along the a-axis direction.
