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-HO hydrogen bonds. The cations and anions are further linked via N-HF and C-HF hydrogen bonds, leading to a sandwich structure .
