Materials Data on Y5Sb3F by Materials Project
Y5Sb3F crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 7-coordinate geometry to five equivalent Sb and two equivalent F atoms. There are a spread of Y–Sb bond distances ranging from 3.06–3.34 Å. Both Y–F bond lengths are 2.81 Å. In the second Y site, Y is bonded in a 6-coordinate geometry to six equivalent Sb atoms. All Y–Sb bond lengths are 3.21 Å. Sb is bonded in a 9-coordinate geometry to nine Y atoms. F is bonded to six equivalent Y atoms to form face-sharing FY6 octahedra.
