Y5Sb3F crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 7-coordinate geometry to five equivalent Sb(1) and two equivalent F(1) atoms. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Y(2) and five equivalent Y(1) atoms. F(1) is bonded to six equivalent Y(1) atoms to form face-sharing FY6 octahedra.
Y5Sb3F crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 7-coordinate geometry to five equivalent Sb(1) and two equivalent F(1) atoms. There are a spread of Y(1)-Sb(1) bond distances ranging from 3.06-3.34 Å. Both Y(1)-F(1) bond lengths are 2.81 Å. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. All Y(2)-Sb(1) bond lengths are 3.21 Å. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Y(2) and five equivalent Y(1) atoms. F(1) is bonded to six equivalent Y(1) atoms to form face-sharing FY6 octahedra.
