Materials Data on EuTmO3 by Materials Project
TmEuO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tm3+ is bonded to six equivalent O2- atoms to form TmO6 octahedra that share corners with six equivalent TmO6 octahedra and faces with eight equivalent EuO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Tm–O bond lengths are 2.13 Å. Eu3+ is bonded to twelve equivalent O2- atoms to form EuO12 cuboctahedra that share corners with twelve equivalent EuO12 cuboctahedra, faces with six equivalent EuO12 cuboctahedra, and faces with eight equivalent TmO6 octahedra. All Eu–O bond lengths are 3.02 Å. O2- is bonded in a linear geometry to two equivalent Tm3+ and four equivalent Eu3+ atoms.
