Abstract
Sodium 12-molybdophosphate hexadecahydrate, Na3PMo12O40·16H2O crystallizes in a monoclinic space group P21/m, with cell dimensions a = 11.4703(4)Å, b = 15.1849(6)Å, c = 13.7083(5)Å, β = 106.902(1)° and V = 2284.51(15)Å3, Z = 2. The final R value is 0.0319 for 5719 reflections (I > 2σ(I)). The crystal is built up of the heteropolyanion (of the Keggin form), six-coordinated sodium ions and water molecules in a 3-D supramolecualr framework, which is produced by some different O-H…O hydrogen bonds.
