Title: Materials Data on CsSeBr3 by Materials Project

Abstract

CsSeBr3 is (Cubic) Perovskite structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. Cs is bonded to twelve Br atoms to form CsBr12 cuboctahedra that share corners with twelve equivalent CsBr12 cuboctahedra, faces with six equivalent CsBr12 cuboctahedra, and faces with eight equivalent SeBr6 octahedra. There are a spread of Cs–Br bond distances ranging from 3.87–3.99 Å. Se is bonded to six Br atoms to form SeBr6 octahedra that share corners with six equivalent SeBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. There are four shorter (2.78 Å) and two longer (2.79 Å) Se–Br bond lengths. There are three inequivalent Br sites. In the first Br site, Br is bonded to four equivalent Cs and two equivalent Se atoms to form a mixture of edge, face, and corner-sharing BrCs4Se2 octahedra. The corner-sharing octahedra tilt angles range from 0–61°. In the second Br site, Br is bonded to four equivalent Cs and two equivalent Se atoms to form a mixture of edge, face, and corner-sharing BrCs4Se2 octahedra. The corner-sharing octahedra tilt angles range from 1–61°. In the third Br site, Br is bonded to four equivalent Cs andmore » two equivalent Se atoms to form a mixture of edge, face, and corner-sharing BrCs4Se2 octahedra. The corner-sharing octahedra tilt angles range from 0–61°.« less
