In the title salt, C17H19N4+·PF6-, the two pyridine rings of the cation are inclined to one another by 15.89 (8)°, and inclined to the imidazole ring by 65.05 (10) and 64.07 (10)°. In the crystal, the cations and anions are linked via a series of C-HN and C-HF hydrogen bonds, forming two-dimensional networks lying parallel to (001).
