Title: Materials Data on Sr3Mn4O12 by Materials Project

Abstract

Sr3Mn4O12 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with six equivalent SrO12 cuboctahedra, corners with six equivalent MnO6 octahedra, faces with six equivalent SrO12 cuboctahedra, and faces with six equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 11°. There are six shorter (2.76 Å) and six longer (2.90 Å) Sr–O bond lengths. In the second Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with three equivalent SrO12 cuboctahedra, and faces with eight MnO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.76–2.88 Å. There are two inequivalent Mn+4.50+ sites. In the first Mn+4.50+ site, Mn+4.50+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with three equivalent SrO12 cuboctahedra, corners with three equivalent MnO6 octahedra, faces with four equivalent SrO12 cuboctahedra, and a faceface with one MnO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There is three shorter (1.91 Å) and three longer (1.93 Å) Mn–O bond length.more » In the second Mn+4.50+ site, Mn+4.50+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with three equivalent MnO6 octahedra, faces with seven SrO12 cuboctahedra, and a faceface with one MnO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There is three shorter (1.90 Å) and three longer (1.91 Å) Mn–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four Sr2+ and two equivalent Mn+4.50+ atoms. In the second O2- site, O2- is bonded in a distorted L-shaped geometry to three Sr2+ and two Mn+4.50+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to two equivalent Sr2+ and two equivalent Mn+4.50+ atoms.« less
