Materials Data on Ba2GdMoO6 by Materials Project

Abstract

Ba2GdMoO6 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with four equivalent GdO6 octahedra, and faces with four equivalent MoO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.87–3.22 Å. Gd3+ is bonded to six O2- atoms to form GdO6 octahedra that share corners with six equivalent MoO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 3–12°. There are a spread of Gd–O bond distances ranging from 2.27–2.29 Å. Mo5+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with six equivalent GdO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 3–12°. There are a spread of Mo–O bond distances ranging from 1.98–2.05 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Gd3+, and one Mo5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Ba2+, one Gd3+, and one Mo5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Ba2+, one Gd3+, and one Mo5+ atom.
