Figure 12
2 Å-wide (x1, x4) superspace section of α2-Fe2P2O7 centred at the O3 atom showing a single point of discontinuity per internal space period at half-integer t values, which is not obvious from the electron density. Contours are drawn at the 2 e Å−3 levels. Positional modulation is even more subtle in the x1 and x3 directions and is not shown.
