RbUF5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Rb–F bond distances ranging from 2.84–3.22 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to nine F1- atoms. There are a spread of Rb–F bond distances ranging from 2.82–3.41 Å. There are two inequivalent U4+ sites. In the first U4+ site, U4+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of U–F bond distances ranging from 2.16–2.71 Å. In the second U4+ site, U4+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of U–F bond distances ranging from 2.17–2.47 Å. There are ten inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal planar geometry to one Rb1+ and two equivalent U4+ atoms. In the second F1- site, F1- is bonded in a 3-coordinate geometry to one Rb1+ and two U4+ atoms. In the third F1- site, F1- is bonded in a 4-coordinate geometry to one Rb1+ and three U4+ atoms. In the fourth F1- site, F1- is bonded in a 1-coordinate geometry to three Rb1+ and one U4+ atom. In the fifth F1- site, F1- is bonded in a 2-coordinate geometry to one Rb1+ and two U4+ atoms. In the sixth F1- site, F1- is bonded in a 4-coordinate geometry to three Rb1+ and one U4+ atom. In the seventh F1- site, F1- is bonded in a distorted single-bond geometry to four Rb1+ and one U4+ atom. In the eighth F1- site, F1- is bonded in a 3-coordinate geometry to one Rb1+ and two equivalent U4+ atoms. In the ninth F1- site, F1- is bonded in a linear geometry to two U4+ atoms. In the tenth F1- site, F1- is bonded in a 1-coordinate geometry to three Rb1+ and one U4+ atom.
