Materials Data on RbSbBrF3 by Materials Project
RbSbBrF3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Rb1+ is bonded in a 5-coordinate geometry to three equivalent Br1- and seven F1- atoms. There are a spread of Rb–Br bond distances ranging from 3.57–4.01 Å. There are a spread of Rb–F bond distances ranging from 2.87–3.32 Å. Sb3+ is bonded in a 3-coordinate geometry to two equivalent Br1- and three F1- atoms. Both Sb–Br bond lengths are 3.08 Å. There are a spread of Sb–F bond distances ranging from 1.99–2.01 Å. Br1- is bonded in a 6-coordinate geometry to three equivalent Rb1+, two equivalent Sb3+, and two equivalent F1- atoms. There are one shorter (3.32 Å) and one longer (3.33 Å) Br–F bond lengths. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a 1-coordinate geometry to two equivalent Rb1+ and one Sb3+ atom. In the second F1- site, F1- is bonded in a 1-coordinate geometry to three equivalent Rb1+ and one Sb3+ atom. In the third F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Rb1+, one Sb3+, and two equivalent Br1- atoms.
