The complex 18Crown[6].[NH4][HSO4].2H2O has been prepd. by co-grinding of solid 18Crown[6] ether and solid [NH4][HSO4], while the complex (15Crown[5])3.[NH4]2[H3O][HSO4]3.H2O has been obtained by kneading liq. 15Crown[5] together with solid [NH4][HSO4]. Structural characterization has been achieved on single crystals obtained by recrystn. of the solid products from water
