Title: Materials Data on BaLaMgRuO6 by Materials Project

Abstract

BaMgLaRuO6 crystallizes in the tetragonal I-4 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 four equivalent MgO6 octahedra, and faces with four equivalent RuO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.72–3.04 Å. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six equivalent RuO6 octahedra and faces with four equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–22°. All Mg–O bond lengths are 2.09 Å. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.50 Å) and four longer (2.83 Å) La–O bond lengths. Ru5+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with six equivalent MgO6 octahedra and faces with four equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–22°. There is two shorter (1.98 Å) and four longer (1.99 Å) Ru–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to two equivalent Ba2+, one Mg2+, two equivalent La3+, andmore » one Ru5+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, one Mg2+, one La3+, and one Ru5+ atom.« less
