abstract	The structure of the title compound, tris(hydroxonium) mu(12)-phosphato-tetracosa-mu(2)-oxo-dodecaoxododecatungsten hexakis(benzo-15-crown-5)-methanol-water (1/1/1), (H3O)(3)[PW12O40].6C(14)H(20)O(5).CH3OH.H2O (where C14H20O5 is benzo-15-crown-5), has been determined at 180 K. [PW12O40](3-) anions are typical of alpha-Keggin structures, and the [H3O.(C14H20O5)(2)](+) sandwich-type moieties contain a large number of short O...O close contacts, suggesting strong hydrogen bonding within them.
