Materials Data on Sr5Bi3 by Materials Project
Sr5Bi3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded to six equivalent Bi atoms to form a mixture of distorted edge, corner, and face-sharing SrBi6 octahedra. The corner-sharing octahedral tilt angles are 35°. All Sr–Bi bond lengths are 3.56 Å. In the second Sr site, Sr is bonded in a 3-coordinate geometry to five equivalent Bi atoms. There are a spread of Sr–Bi bond distances ranging from 3.36–4.03 Å. Bi is bonded in a 9-coordinate geometry to nine Sr atoms.
