Abstract:
The asymmetric unit of the title compound, C(17)H(13)N(4) (+)·BF(4) (-), contains one half of the benzimidazolium cation and one half of the tetra-fluoridoborate anion, with crystallographic mirror planes bis-ecting the mol-ecules. One F atom of the tetra-fluoridoborate is equally disordered about a crystallographic mirror plane. In the crystal, C-H⋯F inter-actions link the cations and anions into layers parallel to (100). The crystal packing is further stabilized by F⋯π contacts involving the tetra-fluoridoborate anions and the five-membered rings [F⋯centroid = 2.811 (2) Å].
