2-Phenyl-4,5-di-2-pyridyl-1H-imidazole

“…In the title compound ( Fig.1), the imidazole and the phenyl ring are nearly coplanar with a dihedral angle of 8.87 (9)° while the two pyridine rings are tilted showing dihedral angels of 11.14 (8) and 20.17 (8)° with respect to the imidazole unit. As compared with related imidazoles having phenyl substituents in 4-and 5-position (Kaftory et al, 1998;Benisvy et al, 2003;Martinez et al, 2004;Seethalakshmi et al, 2006 andThiruvalluvar et al, 2007), the dihedral angels involving pyridine rings and imidazole of the present compound are decreased in value of about 20°. This is presumably attributed to the CH for N exchange being connected with the phenyl for pyridyl substitution, which lowers torsional strain between the two planes defining the dihedral angels.…”
