Title: Materials Data on Sr2MnCrO6 by Materials Project

Abstract

Sr2MnCrO6 is (Cubic) Perovskite-derived structured and crystallizes in the orthorhombic Pmmm 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 twelve SrO12 cuboctahedra, faces with six SrO12 cuboctahedra, faces with four equivalent CrO6 octahedra, and faces with four equivalent MnO6 octahedra. There are ten shorter (2.74 Å) and two longer (2.75 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 SrO12 cuboctahedra, faces with six SrO12 cuboctahedra, faces with four equivalent CrO6 octahedra, and faces with four equivalent MnO6 octahedra. There are two shorter (2.74 Å) and ten longer (2.75 Å) Sr–O bond lengths. Cr6+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with two equivalent CrO6 octahedra, corners with four equivalent MnO6 octahedra, and faces with eight SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There is four shorter (1.94 Å) and two longer (1.95 Å) Cr–O bond length. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners withmore » two equivalent MnO6 octahedra, corners with four equivalent CrO6 octahedra, and faces with eight SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There is four shorter (1.94 Å) and two longer (1.95 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+, one Cr6+, and one Mn2+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to four Sr2+ and two equivalent Cr6+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to four Sr2+ and two equivalent Mn2+ atoms.« less
