Materials Data on Sr2ZnBi2 by Materials Project
Sr2ZnBi2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Sr is bonded in a 3-coordinate geometry to six Bi atoms. There are a spread of Sr–Bi bond distances ranging from 3.37–3.77 Å. Zn is bonded in a distorted trigonal planar geometry to three equivalent Bi atoms. There are two shorter (2.78 Å) and one longer (2.79 Å) Zn–Bi bond lengths. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded in a 6-coordinate geometry to six equivalent Sr atoms. In the second Bi site, Bi is bonded in a distorted trigonal planar geometry to six equivalent Sr and three equivalent Zn atoms.
