Popis: | In the asymmetric unit of the title organic–inorganic hybrid material, 2{H3[PW12O40]}·4C3H4N2O2·C7H8N4O4·21.5H2O, there are four crystallographically independent hydantoin molecules, one dimerized hydantoin molecule, viz. 1,1′-methylenebis(imidazolidine-2,4-dione, two independent H3PW12O40 molecules and 21.5 solvent water molecules. Nine of the solvent water molecules were refined as 0.5 occupancy. The tungstophosphoric acid moieties show characteristic features with respect to the bond lengths and angles. |
