Materials Data on BaLa4Mn5O15 by Materials Project

Abstract

BaLa4Mn5O15 is (Cubic) Perovskite-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with two equivalent BaO12 cuboctahedra, corners with ten LaO12 cuboctahedra, faces with six LaO12 cuboctahedra, and faces with eight MnO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.80–2.90 Å. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with two equivalent BaO12 cuboctahedra, corners with ten LaO12 cuboctahedra, faces with two equivalent BaO12 cuboctahedra, faces with four LaO12 cuboctahedra, and faces with eight MnO6 octahedra. There are a spread of La–O bond distances ranging from 2.65–2.85 Å. In the second La3+ site, La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with three equivalent BaO12 cuboctahedra, corners with nine LaO12 cuboctahedra, a faceface with one BaO12 cuboctahedra, faces with five LaO12 cuboctahedra, and faces with eight MnO6 octahedra. There are a spread of La–O bond distances ranging from 2.65–2.82 Å. There are three inequivalent Mn+3.20+ sites. In the first Mn+3.20+ site, Mn+3.20+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six MnO6 octahedra, a faceface with one BaO12 cuboctahedra, and faces with seven LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–6°. There are a spread of Mn–O bond distances ranging from 1.96–1.98 Å. In the second Mn+3.20+ site, Mn+3.20+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six MnO6 octahedra, faces with two equivalent BaO12 cuboctahedra, and faces with six LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–6°. There is four shorter (1.98 Å) and two longer (1.99 Å) Mn–O bond length. In the third Mn+3.20+ site, Mn+3.20+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six MnO6 octahedra, faces with two equivalent BaO12 cuboctahedra, and faces with six LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 5–6°. There is four shorter (1.97 Å) and two longer (1.99 Å) Mn–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to two equivalent Ba2+, two equivalent La3+, and two equivalent Mn+3.20+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to four La3+ and two equivalent Mn+3.20+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to one Ba2+, three La3+, and two Mn+3.20+ atoms. In the fourth O2- site, O2- is bonded in a distorted linear geometry to one Ba2+, three La3+, and two Mn+3.20+ atoms. In the fifth O2- site, O2- is bonded in a distorted linear geometry to four La3+ and two Mn+3.20+ atoms. In the sixth O2- site, O2- is bonded in a distorted linear geometry to one Ba2+, three La3+, and two Mn+3.20+ atoms.
