Rb3NpH8O9 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 2-coordinate geometry to two O2- atoms. There are one shorter (2.92 Å) and one longer (2.96 Å) Rb–O bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 12-coordinate geometry to four H1+ and eight O2- atoms. There are two shorter (3.01 Å) and two longer (3.14 Å) Rb–H bond lengths. There are a spread of Rb–O bond distances ranging from 2.95–3.20 Å. Np7+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Np–O bond distances ranging from 1.90–2.40 Å. 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 single-bond geometry to one Rb1+ and one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a distorted single-bond geometry to one Rb1+ and one O2- atom. The H–O bond length is 1.01 Å. In the fourth H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.62 Å) H–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to two equivalent H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent Rb1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two Rb1+ and one Np7+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two Rb1+ and one Np7+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Np7+ and two H1+ atoms.
