Materials Data on CsBr3 by Materials Project
CsBr3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs is bonded in a 10-coordinate geometry to ten Br atoms. There are a spread of Cs–Br bond distances ranging from 3.69–4.29 Å. There are three inequivalent Br sites. In the first Br site, Br is bonded in a 5-coordinate geometry to four equivalent Cs and one Br atom. The Br–Br bond length is 2.66 Å. In the second Br site, Br is bonded to four equivalent Cs and one Br atom to form distorted BrCs4Br trigonal bipyramids that share corners with six equivalent BrCs2Br2 tetrahedra, corners with eight equivalent BrCs4Br trigonal bipyramids, an edgeedge with one BrCs2Br2 tetrahedra, and edges with two equivalent BrCs4Br trigonal bipyramids. The Br–Br bond length is 2.52 Å. In the third Br site, Br is bonded to two equivalent Cs and two Br atoms to form distorted BrCs2Br2 tetrahedra that share corners with two equivalent BrCs2Br2 tetrahedra, corners with six equivalent BrCs4Br trigonal bipyramids, and an edgeedge with one BrCs4Br trigonal bipyramid.
