A novel supramolecular organic-inorganic adduct containing alpha-Keggin-type PW12O40(3-) anions and benzo-15-crown-5 molecules

摘要

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 isbenzo-15-crown-5), has been determined at 180 K.[PW12O40]3ÿanions are typical of -Keggin structures, andthe [H3O (C14H20O5)2]+ sandwich-type moieties contain alarge number of short O O close contacts, suggesting stronghydrogen bonding within them.
