Crystal structure of 1-(2,6-diiso-propyl-phen-yl)-1 H -imidazole.

The crystal structure of the title compound, C 15 H 20 N 2 or Dipp Im, is reported. At 106 (2) K, the mol-ecule has monoclinic P 2 1 /c symmetry with four mol-ecules in the unit cell. The imidazole ring is rotated 80.7 (1)° relative to the phenyl ring. Inter-molecular stabilization primarily results from close contacts between the N atom at the 3-position on the imidazole ring and the C-H bond at the 4-position on the neighboring Dipp Im, with ar-yl-aryl distances outside of the accepted distance of 5 Å for π-stacking.
