Abstract
The structures ethanol solvated complexes of parasulphonatocalix4arene with magnesium and calcium have been determined Both show the classical bilayer structure of parasulphonatocalix4arene The cations are situated between the bilayers In the case of the magnesium complex the cation is octahedrally coordinated by six water molecules however for the calcium complex the cation is coordinated in two different geometries by water molecules bridging oxygen atoms of the sulphonate anions and an oxygen of an ethanol molecule Both complexes contain an ethanol molecule embedded in the macrocyclic cavity
