Title: Materials Data on CsAuBr3 by Materials Project

Abstract

CsAuBr3 crystallizes in the tetragonal I4/mmm 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 AuBr6 octahedra. There are four shorter (3.99 Å) and eight longer (4.07 Å) Cs–Br bond lengths. There are two inequivalent Au2+ sites. In the first Au2+ site, Au2+ is bonded to six Br1- atoms to form distorted AuBr6 octahedra that share corners with six equivalent AuBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.52 Å) and two longer (3.40 Å) Au–Br bond lengths. In the second Au2+ site, Au2+ is bonded to six Br1- atoms to form AuBr6 octahedra that share corners with six equivalent AuBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.46 Å) and four longer (3.09 Å) Au–Br bond lengths. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted single-bond geometry to four equivalent Cs1+ and two Au2+ atoms. In the second Br1- site,more » Br1- is bonded in a 6-coordinate geometry to four equivalent Cs1+ and two Au2+ atoms.« less
