description: RbUSO6F crystallizes in the orthorhombic Pca2_1 space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.97–3.35 Å. In the second Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to five O2- and one F1- atom. There are a spread of Rb–O bond distances ranging from 2.93–3.19 Å. The Rb–F bond length is 3.20 Å. In the third Rb1+ site, Rb1+ is bonded in a 12-coordinate geometry to seven O2- and two F1- atoms. There are a spread of Rb–O bond distances ranging from 2.99–3.34 Å. There are one shorter (3.18 Å) and one longer (3.23 Å) Rb–F bond lengths. There are three inequivalent U6+ sites. In the first U6+ site, U6+ is bonded to five O2- and two F1- atoms to form distorted UO5F2 pentagonal bipyramids that share corners with two UO5F2 pentagonal bipyramids and corners with three SO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.80–2.41 Å. Both U–F bond lengths are 2.35 Å. In the second U6+ site, U6+ is bonded to five O2- and two F1- atoms to form distorted UO5F2 pentagonal bipyramids that share corners with two UO5F2 pentagonal bipyramids and corners with three SO4 tetrahedra.

In the third S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three UO5F2 pentagonal bipyramids. There is one shorter (1.46 Å) and three longer (1.50 Å) S–O bond length. There are eighteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Rb1+ and one U6+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Rb1+ and one U6+ atom.
