Analysis of simulated PDFs of well known cluster structures. (a) Simulated PDFs of a decatungstate polyoxometallate cluster from the Na5(H7W12O42)(H2O)20 crystal structure (blue) (Redrup & Weller, 2009), a C60 buckyball from a single unit cell of a C60 crystal structure (green) (Chen & Yamanaka, 2002) and a paratungstate polyoxometallate cluster obtained from the (Ba(H2O)2{H[N(CH3)2]CO}3)2(W10O32){H[N(CH3)2]CO}2 crystalline model (red) (Poimanova et al., 2015). Simulation parameters were chosen to mimic typical measured PDF datasets and are listed in Section A in the supporting information. (b)–(d) Results of using ClusterFinder on the three simulated PDFs where the atoms with the (b) 40, (c) 60 and (d) 12 atoms with the lowest values have been coloured yellow, while the rest are coloured blue. Section C in the supporting information shows a similar representation but where the atom-removal values are directly shown using a continuous colour bar. Oxygen atoms are coloured red and polyhedra are coloured according to their metal atom centre. |
