Figure 1 (a) View of a layer in the thortveitite structure (ab projection). Diorthogroups X2O7 are represented as yellow tetra­hedra and MO6 octa­hedra in dark cyan. (b) View of thortveitite-like structure of Y0.76Ho0.24FeGe2O7 (ac projection). Diorthogroups Ge2O7 are represented as yellow tetra­hedra, while FeO6 octa­hedra appear in light gray, and (Y,Ho)O7 polyhedra (medium slate blue). The bridging O atoms of Ge2O7 groups are displaced up (u) and down (d) normal to the cb plane from its original position in thortveitite.
