Materials Data on BaLaMgNbO6 by Materials Project
BaLaMgNbO6 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal I-4 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 LaO12 cuboctahedra, faces with four equivalent MgO6 octahedra, and faces with four equivalent NbO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.87–2.89 Å. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six equivalent NbO6 octahedra, faces with four equivalent BaO12 cuboctahedra, and faces with four equivalent LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. All Mg–O bond lengths are 2.06 Å. La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with twelve equivalent LaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with four equivalent MgO6 octahedra, and faces with four equivalent NbO6 octahedra. There are a spread of La–O bond distances ranging from 2.87–2.89 Å. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six equivalent MgO6 octahedra, faces with four equivalent BaO12 cuboctahedra, and faces with four equivalent LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. All Nb–O bond lengths are 2.01 Å. 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+, and one Nb5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to two equivalent Ba2+, one Mg2+, two equivalent La3+, and one Nb5+ atom.
