Figure 10
2 Å-wide (x2, x4) superspace section at the origin (position of the bridging O4 atom) of α2-Fe2P2O7 showing a single point of discontinuity per internal space period at half-integer t values. Contours are drawn at the 2 e Å−3 levels. The refined centre of gravity of the O4 atom is represented by a blue line. Positional modulation is distinctly less pronounced in the x1 and x3 directions and is not shown.
