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 with (a) a W9SiO34 fragment from a Keggin-based Na2[C(NH2)3]2[[(CH3)2Sn(H2O)]3(A-α-SiW9O34)]·10H2O crystal (Piedra-Garza et al., 2009BB55), (b) a W12O36 fragment from the crystal structure of a porous framework based on Keggin polyoxoanions, K2NaH2[BW12O40]·12H2O (Han et al., 2012BB32), (c) a W20O64 fragment from a pseudo-Keggin-based crystal with chemical composition H2−xBi2W20O70(HWO3) (Patrut et al., 2010BB53), (d) an SbW9O30 fragment from a K11[Sb3(SiW9O34)2]·31H2O crystal structure (Assran et al., 2012BB7) and (e) a V15O42 fragment from the bicapped Keggin structure (TMA)3H6VV15042·2.5H20 (TMA = tetra­methyl­ammonium) (Hou et al., 1993BB33). W is shown in brown, Sb in grey, O in red, Si in blue and V in pink. Refinement parameters are reported in Section D in the supporting information.
