Materials Data on Rb2S2O7 by Materials Project

Rb2S2O7 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 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.95–3.29 Å. In the second 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 2.96–3.14 Å. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form corner-sharing SO4 tetrahedra. There are a spread of S–O bond distances ranging from 1.45–1.69 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form corner-sharing SO4 tetrahedra. There is three shorter (1.46 Å) and one longer (1.68 Å) S–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+ and two S6+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two Rb1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to three Rb1+ and one S6+ atom.
