Materials Data on SrLa3Mn4O12 by Materials Project

SrLa3Mn4O12 is Orthorhombic Perovskite-derived structured and crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Sr2+ is bonded in a 12-coordinate geometry to nine O2- atoms. There are three shorter (2.54 Å) and six longer (2.84 Å) Sr–O bond lengths. La3+ is bonded in a 3-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.45–2.79 Å. There are two inequivalent Mn+3.25+ sites. In the first Mn+3.25+ site, Mn+3.25+ is bonded to six equivalent O2- atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 20°. All Mn–O bond lengths are 2.00 Å. In the second Mn+3.25+ site, Mn+3.25+ is bonded to six O2- atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedra tilt angles range from 15–20°. There is two shorter (1.99 Å) and four longer (2.00 Å) Mn–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to one Sr2+, two equivalent La3+, and two Mn+3.25+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent La3+ and two equivalent Mn+3.25+ atoms. In the third O2- site, O2- is bonded in a 5-coordinate geometry to one Sr2+, two equivalent La3+, and two equivalent Mn+3.25+ atoms.
