Materials Data on Ba2Bi by Materials Project
Ba2Bi crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Ba sites. In the first Ba site, Ba is bonded in a distorted square co-planar geometry to four equivalent Bi atoms. All Ba–Bi bond lengths are 3.74 Å. In the second Ba site, Ba is bonded in a 5-coordinate geometry to five equivalent Bi atoms. There are one shorter (3.60 Å) and four longer (3.91 Å) Ba–Bi bond lengths. Bi is bonded in a 9-coordinate geometry to nine Ba atoms.
