RbU2C4H5O15 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Rb1+ is bonded in a 9-coordinate geometry to one H1+ and eight O2- atoms. The Rb–H bond length is 2.90 Å. There are a spread of Rb–O bond distances ranging from 2.94–3.28 Å. U4+ is bonded to seven O2- atoms to form distorted corner-sharing UO7 pentagonal bipyramids. There are a spread of U–O bond distances ranging from 1.80–2.49 Å. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.27 Å) C–O bond length. In the second C4+ site, C4+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.27 Å) C–O bond length. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.65 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one Rb1+ and one O2- atom. The H–O bond length is 0.97 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one U4+ and one C4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent U4+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+, one U4+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a water-like geometry to two equivalent Rb1+ and two equivalent H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to three H1+ atoms. In the sixth O2- site, O2- is bonded in a single-bond geometry to one U4+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one U4+ and one C4+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+, one U4+, and one C4+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+ and one U4+ atom.
