Materials Data on TmBeO3 by Materials Project
BeTmO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Be is bonded to six equivalent O atoms to form BeO6 octahedra that share corners with six equivalent BeO6 octahedra and faces with eight equivalent TmO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Be–O bond lengths are 1.77 Å. Tm is bonded to twelve equivalent O atoms to form TmO12 cuboctahedra that share corners with twelve equivalent TmO12 cuboctahedra, faces with six equivalent TmO12 cuboctahedra, and faces with eight equivalent BeO6 octahedra. All Tm–O bond lengths are 2.50 Å. O is bonded in a distorted linear geometry to two equivalent Be and four equivalent Tm atoms.
