Complexs of very long polythers and alkali metal salts can be predicted to have two types of structures: 1) the polyether could wrap spherically around the cation and thus shield it from the anion, and 2) the polyether could adopt an S-shaped arrangement with each loop coordinating a cation, which is still bound to an anion for geometric reasons. These two types have been accomplished in (1) (cation: Rb+) and (2) (salt: 2KSCN).
