Materials Data on Ba2LuReO6 by Materials Project

Abstract

Ba2LuReO6 is (Cubic) Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with four equivalent LuO6 octahedra, and faces with four equivalent ReO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.90–3.03 Å. Lu3+ is bonded to six O2- atoms to form LuO6 octahedra that share corners with six equivalent ReO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 3–4°. All Lu–O bond lengths are 2.20 Å. Re5+ is bonded to six O2- atoms to form ReO6 octahedra that share corners with six equivalent LuO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 3–4°. There is two shorter (1.99 Å) and four longer (2.00 Å) Re–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Lu3+, and one Re5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Lu3+, and one Re5+ atom. In the third O2- site, O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Lu3+, and one Re5+ atom.
