Title: Materials Data on Sr2La2Mn4O11 by Materials Project

Abstract

Sr2La2Mn4O11 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr2+ is bonded in a distorted q6 geometry to ten O2- atoms. There are eight shorter (2.77 Å) and two longer (2.81 Å) Sr–O bond lengths. La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with four equivalent LaO12 cuboctahedra, faces with four equivalent LaO12 cuboctahedra, faces with four equivalent MnO6 octahedra, and faces with four equivalent MnO5 square pyramids. There are eight shorter (2.78 Å) and four longer (2.82 Å) La–O bond lengths. There are two inequivalent Mn3+ sites. In the first Mn3+ site, Mn3+ is bonded to five O2- atoms to form MnO5 square pyramids that share corners with five equivalent MnO6 octahedra and faces with four equivalent LaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There is four shorter (1.92 Å) and one longer (1.99 Å) Mn–O bond length. In the second Mn3+ site, Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share a cornercorner with one MnO6 octahedra, corners with five equivalent MnO5 square pyramids, and faces with four equivalent LaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are a spread ofmore » Mn–O bond distances ranging from 1.87–2.06 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to two equivalent Sr2+, two equivalent La3+, and two Mn3+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to four equivalent La3+ and two Mn3+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+ and two equivalent Mn3+ atoms.« less
