Title: Materials Data on Ba3LaIrRuO9 by Materials Project

Abstract

Ba3LaRuIrO9 crystallizes in the hexagonal P6_3mc 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 three shorter (2.86 Å) and six longer (3.01 Å) Ba–O bond lengths. In the second Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are three shorter (2.85 Å) and six longer (3.01 Å) Ba–O bond lengths. In the third Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra, faces with two equivalent LaO6 octahedra, faces with three equivalent RuO6 octahedra, and faces with three equivalent IrO6 octahedra. There are six shorter (3.00 Å) and six longer (3.01 Å) Ba–O bond lengths. La3+ is bonded to six O2- atoms to form LaO6 octahedra that share corners with three equivalent RuO6 octahedra, corners with three equivalent IrO6 octahedra, and faces with two equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 2–4°. There are three shorter (2.33 Å) and three longer (2.36 Å) La–O bond lengths. Ru5+ is bonded to six O2- atoms to form RuO6 octahedramore » that share corners with three equivalent LaO6 octahedra, faces with three equivalent BaO12 cuboctahedra, and a faceface with one IrO6 octahedra. The corner-sharing octahedral tilt angles are 4°. There are three shorter (1.95 Å) and three longer (2.08 Å) Ru–O bond lengths. Ir4+ is bonded to six O2- atoms to form IrO6 octahedra that share corners with three equivalent LaO6 octahedra, faces with three equivalent BaO12 cuboctahedra, and a faceface with one RuO6 octahedra. The corner-sharing octahedral tilt angles are 2°. There are three shorter (1.97 Å) and three longer (2.06 Å) Ir–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to three Ba2+, one La3+, and one Ru5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to three Ba2+, one La3+, and one Ir4+ atom. In the third O2- site, O2- is bonded to four Ba2+, one Ru5+, and one Ir4+ atom to form a mixture of distorted corner and face-sharing OBa4IrRu octahedra. The corner-sharing octahedra tilt angles range from 4–60°.« less
