Materials Data on TmScO3 by Materials Project

TmScO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tm3+ is bonded to twelve equivalent O2- atoms to form TmO12 cuboctahedra that share corners with twelve equivalent TmO12 cuboctahedra, faces with six equivalent TmO12 cuboctahedra, and faces with eight equivalent ScO6 octahedra. All Tm–O bond lengths are 2.83 Å. Sc3+ is bonded to six equivalent O2- atoms to form ScO6 octahedra that share corners with six equivalent ScO6 octahedra and faces with eight equivalent TmO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Sc–O bond lengths are 2.00 Å. O2- is bonded in a distorted linear geometry to four equivalent Tm3+ and two equivalent Sc3+ atoms.
