Abstract: In the title compound, C11H18N42+·2PF6-, the dihedral angle between the two planar imidozlium rings is 6.1 (2)°. Both [PF6]- anions are disordered [occupancies 0.65 (2):0.35 (2) and 0.59 (5):0.41 (5)]. The crystal packing is stabilized by intermolecular C-HF hydrogen bonds which link two molecules, forming centrosymmetric dimers.
