Abstract: In the title compound, 2C11H18N+·2PF6-·C12H24O6, the 18-crown-6 mol­ecule has crystallographically imposed inversion symmetry. In the crystal, it inter­acts with the cation through weak C-H...O hydrogen bonds. The cations and anions are further linked via N-H...F and C-H...F hydrogen bonds, leading to a sandwich structure .
