abstract: In the title compound, 2C11H18N(+)·2PF6 (-)·C12H24O6, the 18-crown-6 mol-ecule has crystallographically imposed inversion symmetry. In the crystal, it inter-acts 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 .
