Abstract: The structure of the title compound, tris(hydroxonium) 12- phosphato-tetracosa- 2-oxo-dodecaoxododecatungsten hexakis( benzo-15-crown-5)±methanol±water (1/1/1), (H3O)3- [PW12O40] 6C14H20O5 CH3OH H2O (where C14H20O5 is benzo-15-crown-5), has been determined at 180 K. [PW12O40]3ÿ anions are typical of -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.
