Materials Data on CsScBr3 by Materials Project
CsScBr3 is (Cubic) Perovskite structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. Cs1+ is bonded to twelve Br1- atoms to form CsBr12 cuboctahedra that share corners with twelve equivalent CsBr12 cuboctahedra, faces with six equivalent CsBr12 cuboctahedra, and faces with eight equivalent ScBr6 octahedra. There are a spread of Cs–Br bond distances ranging from 3.86–3.95 Å. Sc2+ is bonded to six Br1- atoms to form ScBr6 octahedra that share corners with six equivalent ScBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. All Sc–Br bond lengths are 2.76 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted linear geometry to four equivalent Cs1+ and two equivalent Sc2+ atoms. In the second Br1- site, Br1- is bonded in a distorted linear geometry to four equivalent Cs1+ and two equivalent Sc2+ atoms. In the third Br1- site, Br1- is bonded in a distorted linear geometry to four equivalent Cs1+ and two equivalent Sc2+ atoms.
