The host molecules (4a–d), containing two crownether ring systems, form 1 : 1 complexes (8) with the bis primary alkylammonium salt (7); in the cases of the host (4a) and (4b) guest–host fit is so good that only the intramolecularcomplex is formed, but for the other host molecules (4c) and (4d) the complex (8) is probably accompanied by the polymeric complex (9).
