In the cation of the title salt, C(24)H(24)N(7) (3+)·3C(6)H(2)N(3)O(7) (-)·2C(2)H(3)N, the three benzimidazolium ring systems are oriented to each other at dihedral angles of 10.42 (7), 23.98 (7) and 22.17 (7)°. In the crystal, the cation links to the adjacent picrate anions via N-H⋯O hydrogen bonds; one of independent acetonitrile solvent mol-ecules is also linked to the cation via an N-H⋯N hydrogen bond.
