Hydrogen bonding in 1H-naphth[2,3-d]imidazole

R. T. Stibrany, H. J. Schugar and J. A. Potenza

Abstract: The title compound, C₁₁H₈N₂, contains two essentially planar molecules (A and B) in the asymmetric unit. Molecules of type B exhibit - stacking and form infinite zigzag chains along the a axis. A and B molecules are linked by N_amine-HN_imine hydrogen bonds and form polymeric -A-B-A-B- criss-crossed chains approximately along the [110] and [10] directions. The A molecules show little evidence of stacking and, in addition to the hydrogen bonds, appear to be held in the crystal structure primarily by C-H interactions. The geometric parameters of molecules A and B agree well with each other and, where comparisons are appropriate, with those of a naphthimidazolium cation.
