Figure 2
(a) A generic representation of the V2O7 unit in the ZrV2O7 structure and (b) its breakdown for structural model building. V2O7 is divided into two equal parts [V(O1)3O3]2 (denoted with different colors) from part (a) to part (b), in order to be consistent with the [W2(O1)3O3]2 unit in ZrW2O8. The occupancy fraction of each O3 congener in [V(O1)3O3]2 is half that of V. Displacement ellipsoids are drawn at the 75% probability level.
