Fig. 8: Experimental PDF from Keggin clusters in solution.

a Comparison of experimental data from a 0.05 M ammonium metatungstate hydrate solution, and simulated PDFs from the four different starting models [1]–[4]. The simulation parameters mimic typical values of a PDF dataset and can be seen in Supplementary Table 3. b The W12O40 α-Keggin structure.
