In the title compound, C 8 H 8 N 2 ·C 8 H 9 N 2 + ·PF 6 − , 50% of the N ‐methylbenzimidazole residues are protonated. An N—H⋯N + hydrogen bond with a D ⋯ A distance of 2.641 (2) Å is formed. The organic molecules are located on crystallographic mirror planes and the PF 6 − counter‐ions are located on crystallographic 2/ m sites.
