Sumario:In the asymmetric unit of the title organic–inorganic hybrid material, 2{H(3)[PW(12)O(40)]}·4C(3)H(4)N(2)O(2)·C(7)H(8)N(4)O(4)·21.5H(2)O, there are four crystallographically independent hydantoin mol­ecules, one dimerized hydantoin mol­ecule, viz. 1,1′-methyl­enebis(imidazolidine-2,4-dione, two independent H(3)PW(12)O(40) 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.
