Cover illustration: The structure of hydronium bis(trifluoromethanesulfonyl)amide-18-crown-6 (1/1), [H3O+·C12H24O6][N(SO2CF3)2-], which is an ionic liquid with a melting point of 341-343 K, has been determined at 113 K. The asymmetric unit consists of two crystallographically independent 18-crown-6 molecules, two hydronium ions and two bis(trifluoromethanesulfonyl)amide anions. One hydronium ion is complexed with an ordered 18-crown-6 molecule with H2OHOC distances of 1.90-2.19 Å, and the other hydronium ion with a disordered 18-crown-6 molecule with distances of 1.85-2.36 Å.
