Fig. 11. Diagrammatic representation of the maximal (red) and minimal (blue) averaged interatomic (V⋯V) distances within α-{V18−x(As2)xO42} (dark shaded) and β-{V18−x(As2)xO42} (light shaded) systems. Selection of the single interatomic for x = 2 for both systems is projected left to the diagram. The structurally inequivalent V centres are coloured differently, namely μ4-V = dark blue, μ3-V = yellow and μ2-V = light blue.
