Figure 1
The unique oxidodisilicate [Si2O7]6− anion composed of two vertex-connected [SiO4]4− tetra­hedra in M-type Gd2[Si2O7], where the position of the O atoms define a horseshoe arrangement (left), and its Newman projection (right). Displacement ellipsoids are drawn at the 95% probability level. The symmetry codes are available in Table 1[link].
