Fig. 8. Fit of the skewed (Fe6(FeW9O34))2 cluster, stemming from the (Ni6(H2O)9(OH)3(HSiW9O34))2(H2O)12 structure to the FeWO4 precursor PDF. Zoom factor for the cluster related to the crystallographic directions of the parent crystal structure, scale factor, isotropic atomic displacement factors and δ2 were refined.
