Materials Data on Ba2Bi3 by Materials Project
Ba2Bi3 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Ba is bonded in a 8-coordinate geometry to eight Bi atoms. There are a spread of Ba–Bi bond distances ranging from 3.68–3.81 Å. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded in a 9-coordinate geometry to six equivalent Ba and three Bi atoms. There are one shorter (3.26 Å) and two longer (3.38 Å) Bi–Bi bond lengths. In the second Bi site, Bi is bonded in a 8-coordinate geometry to four equivalent Ba and four equivalent Bi atoms.
