Materials Data on Zr5Sn3As by Materials Project
Zr5Sn3As crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Zr sites. In the first Zr site, Zr is bonded in a 6-coordinate geometry to six equivalent Sn atoms. All Zr–Sn bond lengths are 3.06 Å. In the second Zr site, Zr is bonded in a 7-coordinate geometry to five equivalent Sn and two equivalent As atoms. There are a spread of Zr–Sn bond distances ranging from 2.98–3.20 Å. Both Zr–As bond lengths are 2.72 Å. Sn is bonded in a 9-coordinate geometry to nine Zr atoms. As is bonded to six equivalent Zr atoms to form face-sharing AsZr6 octahedra.
