Materials Data on Gd2Ru2O7 by Materials Project
Gd2Ru2O7 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Gd3+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are two shorter (2.23 Å) and six longer (2.51 Å) Gd–O bond lengths. Ru4+ is bonded to six equivalent O2- atoms to form corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles are 50°. All Ru–O bond lengths are 2.01 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Gd3+ and two equivalent Ru4+ atoms to form a mixture of distorted corner and edge-sharing OGd2Ru2 tetrahedra. In the second O2- site, O2- is bonded to four equivalent Gd3+ atoms to form a mixture of corner and edge-sharing OGd4 tetrahedra.
