POMFinder's top five predictions on experimental fast-acquisition X-ray PDF data. Comparisons of the PDF from a 0.05 M solution of ammonium metatungstate in oleylamine heated to 200°C for 4 min and the calculated PDF of (a) a W48O152 fragment from the polyanion K26.5Li9.5[H4As8W48O184]·90H2O (Mbomekallé et al., 2014), (b) a W12O42 fragment from the acidic sodium polytungstate Na5[H7W12O42]·20H2O (Redrup & Weller, 2009), (c) a W11K3O38 fragment from the crystal structure K6H4W11O38·H2O (Lehmann & Fuchs, 1988), (d) a W2O7 fragment from the crystal structure of Bi2W2O9 (Champarnaud-Mesjard et al., 1999) and (e) an Re2O8 fragment from the crystal structure Bi28Re2O49 (Crumpton et al., 2005). W is shown in brown, K in grey, O in red, Si in blue and Re in green. Refinement parameters are reported in Section D in the supporting information. |
