✦ Synopsis

The title compound, C 11 H 8 N 2 , contains two essentially planar molecules (A and B) in the asymmetric unit. Molecules of type B exhibit %±% stacking and form in®nite zigzag chains along the a axis. A and B molecules are linked by N amine ÐHÁ Á ÁN imine hydrogen bonds and form polymeric ±A±B±A±B± crisscrossed chains approximately along the [110] and [110] 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 CÐHÁ Á Á% 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.
