2-(4,5-Dihydro-1H-imidazol-2-yl)pyridine

R. Kia, H.-K. Fun and H. Kargar

Abstract: In the molecule of the title compound, C₈H₉N₃, a new imidazoline derivative, the six- and five-membered rings are slightly twisted away from each other, forming a dihedral angle of 7.96 (15)°. In the crystal structure, neighbouring molecules are linked together by intermolecular N-HN hydrogen bonds into extended one-dimensional chains along the a axis. The pyridine N atom is in close proximity to a carbon-bound H atom of the imidazoline ring, with an HN distance of 2.70 Å, which is slightly shorter than the sum of the van der Waals radii of these atoms (2.75 Å). The crystal structure is further stabilized by intermolecular C-H and - interactions (centroid-to-centroid distance 3.853 Å).
