Materials Data on CsSmCl3 by Materials Project
CsSmCl3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent Cl1- atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent CsCl12 cuboctahedra, faces with six equivalent CsCl12 cuboctahedra, and faces with eight equivalent SmCl6 octahedra. All Cs–Cl bond lengths are 3.89 Å. Sm2+ is bonded to six equivalent Cl1- atoms to form SmCl6 octahedra that share corners with six equivalent SmCl6 octahedra and faces with eight equivalent CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Sm–Cl bond lengths are 2.75 Å. Cl1- is bonded in a distorted linear geometry to four equivalent Cs1+ and two equivalent Sm2+ atoms.
