Materials Data on Gd3RuO7 by Materials Project
Gd3RuO7 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded to seven O2- atoms to form distorted GdO7 pentagonal bipyramids that share corners with two equivalent RuO6 octahedra, corners with three equivalent GdO7 pentagonal bipyramids, edges with two equivalent RuO6 octahedra, and edges with two equivalent GdO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 37°. There are a spread of Gd–O bond distances ranging from 2.24–2.54 Å. In the second Gd3+ site, Gd3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.35 Å) and four longer (2.68 Å) Gd–O bond lengths. Ru5+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with two equivalent RuO6 octahedra, corners with four equivalent GdO7 pentagonal bipyramids, and edges with four equivalent GdO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 38°. There is four shorter (1.97 Å) and two longer (1.98 Å) Ru–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Gd3+ and two equivalent Ru5+ atoms. In the second O2- site, O2- is bonded to four Gd3+ atoms to form a mixture of edge and corner-sharing OGd4 tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Gd3+ and one Ru5+ atom.
