Average O—O distances and Δ〈O—O〉 deviation parameter in the V1O6 (full symbols) and V2O6 (open symbols) octa­hedra of the average structure (P2/m, Z = 2). The deviation parameter is defined as Δ〈O—O〉 = [ \left( \sum _{i=1}^{12} \left\vert {\rm OO}_i - {\rm OO}_m \right\vert \right) / 12 {\rm OO}_m].
