Materials Data on RbSO4F by Materials Project
RbSO4F crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Rb is bonded in a 11-coordinate geometry to nine O and two equivalent F atoms. There are a spread of Rb–O bond distances ranging from 3.04–3.39 Å. There are one shorter (3.14 Å) and one longer (3.28 Å) Rb–F bond lengths. S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.45–1.68 Å. There are four inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to three equivalent Rb and one S atom. In the second O site, O is bonded in a single-bond geometry to three equivalent Rb and one S atom. In the third O site, O is bonded in a distorted single-bond geometry to two equivalent Rb and one S atom. In the fourth O site, O is bonded in a distorted water-like geometry to one Rb, one S, and one F atom. The O–F bond length is 1.50 Å. F is bonded in a distorted single-bond geometry to two equivalent Rb and one O atom.
