Materials Data on CsTmCl3 by Materials Project
CsTmCl3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Cs is bonded to twelve equivalent Cl atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent CsCl12 cuboctahedra, faces with six equivalent CsCl12 cuboctahedra, and faces with eight equivalent TmCl6 octahedra. All Cs–Cl bond lengths are 3.76 Å. Tm is bonded to six equivalent Cl atoms to form TmCl6 octahedra that share corners with six equivalent TmCl6 octahedra and faces with eight equivalent CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Tm–Cl bond lengths are 2.66 Å. Cl is bonded in a distorted linear geometry to four equivalent Cs and two equivalent Tm atoms.
