The complexes 18 C 6 · 2 HN (SO 2 -2 -Naphthyl) 2  (2a) and 18 C 6 · 2  i PrOH · 2 HN (SO 2 Ph) 2  (3e) were obtained by co-crystallization of 18-crown-6 (18 C 6) with the appropriate di(arenesulfonyl) amine from isopropanol solutions at temperatures ≥20 °C (for 2a) or at - 20 °C (for 3e). Both structures contain isolated formula units displaying crystallographic inversion symmetry. The conformation of the crown rings is characterized by the torsion angle sequence g + g + aag − g + ag + ag − g − aag + g − ag − a, unprecedented in solid-state structures of 18C 6 complexes. The six ether oxygen atoms and four out of twelve carbon atoms of the ring are coplanar within ± 7 pm. In 2a (triclinic, space group P 1̄) , the disulfonylamine molecules are linked to the oxygen atoms of the g ± g ∓ g ∓  units via N -H ··· O hydrogen bonds ( H ··· O 201 pm, N - H ··· O 161°). In 3e (triclinic, space group P 1̄ ) , each amine is N - H ··· O bonded to an isopropanol molecule (H ··· O 193 pm , N - H ··· O 175°) that is connected to a crown oxygen atom of the same conformational type as indicated above for 2a (H ··· O 198 pm, O - H ··· O 166°).
