Materials Data on SnBi by Materials Project

SnBi crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Sn is bonded in a 5-coordinate geometry to five equivalent Sn and six equivalent Bi atoms. There are a spread of Sn–Sn bond distances ranging from 3.13–3.48 Å. There are a spread of Sn–Bi bond distances ranging from 3.33–3.62 Å. Bi is bonded in a 10-coordinate geometry to six equivalent Sn and four equivalent Bi atoms. There are two shorter (3.39 Å) and two longer (3.43 Å) Bi–Bi bond lengths.
