Title: Materials Data on Gd2MnSbO7 by Materials Project

Abstract

Gd2MnSbO7 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 MnO6 octahedra, and edges with four equivalent SbO6 octahedra. There are a spread of Gd–O bond distances ranging from 2.24–2.55 Å. In the second Gd3+ site, Gd3+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Gd–O bond distances ranging from 2.28–2.59 Å. Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent MnO6 octahedra, corners with four equivalent SbO6 octahedra, and edges with two equivalent GdO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 50–52°. There are two shorter (1.98 Å) and four longer (2.11 Å) Mn–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 MnO6 octahedra, and edges with four equivalent GdO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 47–52°. There are four shortermore » (1.99 Å) and two longer (2.05 Å) Sb–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to four Gd3+ atoms to form OGd4 tetrahedra that share corners with twelve OGd4 tetrahedra and edges with four equivalent OGd2MnSb tetrahedra. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Gd3+ and two equivalent Mn3+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Gd3+ and two equivalent Sb5+ atoms. In the fourth O2- site, O2- is bonded to two Gd3+, one Mn3+, and one Sb5+ atom to form a mixture of distorted corner and edge-sharing OGd2MnSb tetrahedra.« less
