Rb2MnH12(SeO7)2 crystallizes in the monoclinic P2_1/c 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 3.19 Å. There are a spread of Rb–O bond distances ranging from 2.95–3.37 Å. Mn2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Mn–O bond distances ranging from 2.16–2.25 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.75 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. 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 1.00 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.72 Å) H–O bond length. In the sixth 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 (1.68 Å) H–O bond length. Se6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.67–1.69 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one H1+, and one Se6+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Mn2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Rb1+ and one Se6+ atom. In the fourth O2- site, O2- is bonded in a distorted tetrahedral geometry to one Rb1+, two H1+, and one Se6+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+ and one Se6+ atom. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to one Rb1+, one Mn2+, and two H1+ atoms. In the seventh O2- site, O2- is bonded in a distorted water-like geometry to one Rb1+, one Mn2+, and two H1+ atoms.
