Materials Data on CeMnO3 by Materials Project
CeMnO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ce4+ is bonded to twelve equivalent O2- atoms to form CeO12 cuboctahedra that share corners with twelve equivalent CeO12 cuboctahedra, faces with six equivalent CeO12 cuboctahedra, and faces with eight equivalent MnO6 octahedra. All Ce–O bond lengths are 2.77 Å. Mn2+ is bonded to six equivalent O2- atoms to form MnO6 octahedra that share corners with six equivalent MnO6 octahedra and faces with eight equivalent CeO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Mn–O bond lengths are 1.96 Å. O2- is bonded in a distorted linear geometry to four equivalent Ce4+ and two equivalent Mn2+ atoms.
