Title: Materials Data on Gd2InSbO7 by Materials Project

Abstract

Gd2InSbO7 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. there are two inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded to eight O2- atoms to form distorted GdO8 hexagonal bipyramids that share edges with two equivalent GdO8 hexagonal bipyramids, edges with two equivalent InO6 octahedra, and edges with four equivalent SbO6 octahedra. There are a spread of Gd–O bond distances ranging from 2.25–2.68 Å. In the second Gd3+ site, Gd3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Gd–O bond distances ranging from 2.34–2.59 Å. In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with two equivalent InO6 octahedra, corners with four equivalent SbO6 octahedra, and edges with two equivalent GdO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 54–62°. There are two shorter (2.16 Å) and four longer (2.20 Å) In–O bond lengths. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra, corners with four equivalent InO6 octahedra, and edges with four equivalent GdO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 41–54°. There are four shorter (2.00more » Å) and two longer (2.03 Å) Sb–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Gd3+ and two equivalent In3+ atoms to form OGd2In2 tetrahedra that share corners with six OGd2In2 tetrahedra and an edgeedge with one OGd4 tetrahedra. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Gd3+ and two equivalent Sb5+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two Gd3+, one In3+, and one Sb5+ atom. In the fourth O2- site, O2- is bonded to four Gd3+ atoms to form a mixture of edge and corner-sharing OGd4 tetrahedra.« less
