Materials Data on Ba2BiRuO6 by Materials Project
Ba2RuBiO6 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 12-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.91–3.11 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with two equivalent BiO6 octahedra, and faces with six equivalent RuO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.99–3.09 Å. In the third Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with two equivalent RuO6 octahedra, and faces with six equivalent BiO6 octahedra. There are a spread of Ba–O bond distances ranging from 3.06–3.28 Å. Ru5+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with three equivalent BiO6 octahedra, faces with four BaO12 cuboctahedra, and a faceface with one RuO6 octahedra. The corner-sharing octahedra tilt angles range from 7–10°. There are three shorter (1.91 Å) and three longer (2.10 Å) Ru–O bond lengths. Bi3+ is bonded to six O2- atoms to form BiO6 octahedra that share corners with three equivalent RuO6 octahedra, corners with three equivalent BiO6 octahedra, and faces with four BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–10°. There are a spread of Bi–O bond distances ranging from 2.17–2.45 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to four Ba2+, one Ru5+, and one Bi3+ atom. In the second O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two equivalent Ru5+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to four Ba2+, one Ru5+, and one Bi3+ atom. In the fourth O2- site, O2- is bonded in a distorted linear geometry to two equivalent Ba2+ and two equivalent Bi3+ atoms. In the fifth O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two equivalent Ru5+ atoms. In the sixth O2- site, O2- is bonded in a distorted linear geometry to two equivalent Ba2+ and two equivalent Bi3+ atoms.
